Cacheman 1.0-4.1 has been released as Freeware. During the last months the program has been completely rewritten. We are forced to try to get the development costs back. The simplest way for us to achieve this would be to disable certain key features or to convert the distribution to a time limited version. We are opposed to taking the easy way out since we would not like our user base to be reduced drastically. Alternatively, we could bundle Cacheman with a third party software and receive distribution fees. Many Freeware programs are going this path nowadays. We decided not to distribute Cacheman in this way since all software bundles we have examined have a major drawback - the additional third party software spies out user data! (Visit for more information). After a long discussion we have come up with a unique way to license Cacheman:

Some user comments
I find it almost hard to believe that memory problems were the source of poor performance of my computer, since I have 256mb of PC100 installed. But, as I learned from Cacheman, it was not being utilized properly. Now my computer is faster than it has ever been, thanks to the easy to use wizards to help me set everything up correctly. 3D games always ran fast, but they took forever to load up. Normal programs, such as photo editors, also loaded slowly, but they also caused major disk activity during use. Now everything is fast! No slow downs period, with anything! I would have never guessed that Disk Cache settings were the problem (among other settings as well). Thanks alot for a superb product, I am recommending this utility to everyone I know!
L. Ledbet
In my opinion, Cacheman 5 should be a standard part of Windows. It certainly stabilizes it to the point that this PC has become virtually a no-crash/no-hang machine.
...
So: with Cacheman 5, once again: This Aptiva Rocks. Stability is just not a problem anymore, and even the Internet runs faster than before - no memory problems.

I just had to write to thank you for your product. I have a Compaq with 800mhz PIII. The problem was a majority of the time when I attempted to burn a cd I would get underwrite errors even if I was not running any other programs. I thought I could correct this by adding additional ram. After adding another 256mb (bringing my total to 384mb) I would still get the write errors. I heard about Cacheman on CNET and thought I would give it a try. Let me tell you, I wish I had known about this before I went and purchased the additional ram! Since I have loaded Cacheman I have burned over 50 cd's and have not had a single error. But that's not all. I decided to really push it and see what my computer could handle. I added a new burner. I upgraded my burner from 4x write to 24x write. Then started the test. While burning a cd I....
(1) Signed on to AOL (man this takes allot of juice)
(2) Watched music videos online.
(3)Downloaded mp3 files
(4)Created and printed jewel cases
After starting these programs my cd was just about complete and I still had a large amount of available ram. I know that without Cacheman this wouldn't have been possible at all. I barely could burn a cd let alone try to create a jewel case or surf the web, that was a guaranteed burn error. And I enjoy watching my friends facial expressions when I run other programs while I burn a cd. They warn me not to touch anything while I'm burning or I'll have to toss out another cd-r. And I say "No I won't" and I don't!!! Thanks again.

I just want to say that I love your new program Cacheman 5. Cacheman 4.1 was great and made a huge improvement on my system - my PIII 1GHz w/256MB RAM seemed to be more responsive than my friends Athlon 1333Hz w/512MB RAM (or at least it did until he downloaded the program), I was overjoyed when I read that there was a new version. I have yet to see any major performance differences (between 4.1 and 5) but the interface is much better, it gives me quick "wizard" solutions when I need them and the ability to tweak the settings to perfection myself when I have the time. I haven't had the cash to register yet (tuition sucks it all up) but I plan to do so as soon as I get a chance. You guys have created a very professional product that I intend to recommend to all my friends, keep up the good work.
Luke Tudor
I just wanted to say thanks to all involved who made such a great product. I appreciate this because it extends the limited Win9.X environment much further in dealing with memory efficiency. Usually when you hit 512ram at that point you either deal with the non efficient Win9.x or move to NT. For this very reason I am grateful because the resource requirements for NT/XP leap several levels with questionable return.
I highly recommend your product to others that could benefit from such an excellent utility application.

I recently purchased Lionhead's great game Black and White and installed it on my new Dell Dimension 4100. I thought I'd have a smooth experience, but my DVD-ROM and hard drive continually ran and turned fluid gameplay into a slideshow. With all the attempts on my part and even Lionhead tech support, I was only able to reduce the problem, but didn't eliminate it. After downloading and installing Cacheman 4.1, I was able to completely eliminate the problem and every piece of software I have benefits from Cacheman. I highly recommend this product to people as a powerful alternative to memory upgrades.
Matthew Peak
Hi there,
This is not a support request but I'd just like to give you some feedback on Cacheman 4.1.
I read about it on download.com in their essential pc utilities so I downloaded it to give it a try. Even though I have 256mb of RAM, Windows 98 (se) seems to manage it atrociously. I frequently have to reboot due to memory shortages, normally IE5 breaks the system. Also, I thought unconnected, IE5 & Outlook 5 take an age to start up. When I click on them, it opens the window but the actual tool bar does not load for a few seconds and the harddrive thrashes around trying to load them up. I always thought this was a registry error, so I have tried various reg hacks to sort it.
Up steps Cacheman. I couldn't believe it when IE5 & Outlook snapped open as quick as you like, as they should do on a 800mhz system. It had never occured to me that the memory could be the problem.
Thanks for the product,
Pete Gibbins

I suffered about a network slowdown issue for weeks until I was referred to Cacheman. Problem solved. Thanks! I just can't understand why WinME had this problem in the first place.
Here's some history:
This has been driving me nuts:
When I copy and paste files from other computers on my network to the MSI K7T Turbo-Raid, it starts out like gangbusters then drags to a crawl and the mouse will become slow as if it's stuck in mud. Once I cancel the file transfer, the mouse moves freely again. This only occurs ONE WAY, when I working from the K7T-R. If I send files to the same machine from other machines, transfer is smooth and so is the mouse.
...
Any ideas would be highly appreciated. I've hammered this out for days and I'm ready to play for a change! Thanks
~~~~~~~~~~~~~~~~~~~~~~~~
I had this same problem with WinMe and 256 MB ram, download the program "Cacheman" and change the default windows cache settings, when i tried this the problem went away. Just try the power user template :-)
Cacheman is freeware, download here :

You nailed it! I just want to extend my deepest appreciation as I have been hammering this one out for weeks, and I'm not one to ask for help until I've absolutely reached the end of my rope (and I was about to hang myself with it).
I never considered it could be a disk cache issue but I gave Cacheman a shot as a last ditch effort before formatting and going back to 98se. Bingo. My mouse is as free as a bird and file transfers across the network are smooth.
Eddie Puryear
Thanks for Cacheman!!
I was having major problems burning CD's, playing 3D games and was also troubled with slow HD access times when cutting & copying within CoolEdit but thanks to your piece of wizardry, all my problems have been resolved. No more failed burns, no more unexpected crashes in Tomb Raider 4 and best of all, my 700MHz Athlon now acts like it should, fast and transparent to use.
Best regards.

Hey, this program is absolutely fantastic. Yesterday I downloaded the version 4.0 of cacheman. I choosed the first option for novice and intermediate users and I gained 40 Mb Ram. I have a Celeron400, 96 Ram,Voodoo 3 2000..... . Without this utility only 15 Mb Ram were left. In other words this is a super-great-excellent-fantastic program. I have seen a good improvement in speed in games like Red Alert 2, Panzer 3D Assault which require more memory. I tried before other utilities but in vain. At the end I found cacheman. I said in my mind that this will be my last chance and I was victorious. I was super happy.

Hello Outertech and thank you very very much!!!
I recently upgraded to 768MB ram and experienced dying computer syndrome.
I remembered an article in PCA about Cacheman, so I downloaded it, chose Multimedia for ME, and restarted my computer.
Thank you again, I now have a very fast computer with lots of ram, especially lots of free ram!!!
Thank you and keep up the good work.

Dear Thomas,
Thanx for Cacheman 3.80; my problems seem to be over!
I've been having problems running Photoshop 5.5 on a P-III 750MHz system with 384MB Ram... After scanning and editing only a couple of 35MB-files, Photoshop was always getting slower and slower as available Ram decreased to 0. I had to close the program and start it up every 15-20 minutes, and I was considering buying a Mac G4. But now I can keep my money in my pocket!
Cacheman 3.80 works wonderfully; I'm using settings for "multimedia use" and available Ram has not been less than 200MB since... Overall performance and speed in Photoshop remain constant, even after hours and hours of work.
In one word, it's great! So keep up the good work!
Best regards,
Jeroen Bouman
Installing your cacheman program is almost like buying a new computer. I use to have problems with my John Madden2001 sometimes pausing during gameplay, but after installing your program the game now runs as smooth as silk.
Thanx a million

This PC is a bit of an old warhorse - 32MB RAM, P150, bits of it our almost 10 years old so it's often a struggle to run hardcore modern software.
I am a drum & bass producer so as you can imagine I run an awful lot of audio-editing software that this machine can't really cope with. I had a lot of problems with songs skipping, effects not responding quickly enough etc. Basically it was practically impossible to even listen to an mp3 without it skipping every time I ran another program. I changed a multitude of options, tweaked the registry, ran RAM-boosting software and a whole load of other stuff all of which only made a slight difference. After I set Cacheman to Win98 Power User my problems all but disappeared!
You are a genius!

Thank you for releasing such a great product for free! I have been installing it religiously on the computers I build for work and what can I say? It's GREAT! Not a single customer complaint of out of memory errors! I also don't run out of resources anymore on my own workhorse machine a PIII450 with 128MB.
Thank you.

Hi!
I just thought you might want to know that CODEMASTERS (www.codemasters.com a game making company) recommends its customers to use your program Cacheman when they (the customers) have any memory-linked problems with they're very newly released racing game Colin McRae Rally 2.0 .... They seem to like it ALOT!
You might already know this, but if you didn't .... then ... now you know =)
Cheers! / Jonas (from Sweden)
This is really a great little piece of software!!! Today , all my problems seem so far away, yesterday it seem that they were here to stay. Oh I believe in "Cachemanday" (sic The Beatles). Thank you very much!

First, let me say that your program, Cacheman, is the finest piece of freeware for the Windows system in the entire free world. I cannot say enough about how it has made my system run better. Across the board, system, user, and GDI, have all been increased dramatically. I run many servers through my DSL line, web, ftp, mail, and even a ShoutCast internet radio station, and it used to be that I was lucky to have 78% of my resources free after all those servers had fired up and users were on them. Now, I have...drum roll please... a whopping 90% across the board of resources available. So now when I fire up NetObjects Fusion (my web design program) or Bright (my image editing program) they fire up and respond with a bit more alacrity than before I installed Cacheman. Thanks for making that very fine utility available as freeware, I'm sure that you have gained a lot of good karma through offering such a fine piece of software for free.
John Erickson
Just wanted to thank you for Cacheman. I thought you might be interested in the following.
PaintShopPro has a disk based undo system with quite a few configuration settings. The one I like to use saves each individual paint operation so I can undo one step at a time. The only problem with this WAS that it was slow, I mean sloooooow, so slow that the system would pause for 2 or 3 seconds until it caught up. It would also leave fragments of the mouse pointer on screen until the window was refreshed. In short, I spent quite a bit of time looking at a messy screen and the hourglass pointer. Since setting the vcache with Cacheman v3.51 (4096, 4096, 512, 4096, 96) the problem has COMPLETELY vanished. I get only an occasional flash of the hourglass pointer now, no pointer fragments and no delays. This is a truly amazing performance boost, almost like a processor upgrade. Also, the overall performance of my system in general is much smoother and more responsive.

Dear Thomas Reimann,
You've just been nominated to received the "Best Guy Award" for 1998. By chance, I purchased a computer magazine that had system optimization software include--namely one of yours. Thanks a whole bunch. Your program which I perhaps have save me hundreds of dollars from having to go to technicians and buying CD's that were lost during a session gone bad. One thing for sure, I no longer received those undesirable "low buffer runs" from my CD program. The first time I installed Cacheman 3.51, my HP8100 CD Writer worked flawless. In addition, when installing software to my system, my CD ROM would just creep as if it was an old guy. I found that pretty strange and all, because I have a 24X CD ROM and from the most part, on average, it runs fast enough to get a ticket for speeding. Out of the 3 biggest problems I had, your program fix 2. Again, your program is wonder.
...
Again, I would like to say thank you for making this program--its wonderful.Feel free to use part of this message in any type of advertising to let customer know that its not just some other program looking for attention. And by the way, I will share the good news with other friends and well. If you would like for me to add any comments that you have to my Webster that I'm about to make, feel free to send the comment and as soon as it is posted, I send you the web site address. Thanks Thomas.

Read a CD newsgroup that your CacheMan product was a big help in solving under-run errors in burning... They were right. On my PIII/Win98 system with 256MB, loading your program and setting it for 32MB min and Max did the trick.

I have just installed cacheman on my system.
For months I have been trying to solve the problem of my 128mb ram being eaten up by a huge cache file. I have read magazine after magazine and installed diagnostics tools of all shapes and sizes to no avail. I have probably wasted more than 50 hours trying to get to the root of this problem. I am really impressed that you have explained what the system does in terms of adjusting the system.ini file. If Microsoft had the same sense of trying to help people understand how their system works instead of blinding us with jargon life would be so much easier. With Cacheman however it's even easier and there's no guesswork involved.
Well Done!
Thank you for solving my biggest computer headache for years.

Hello Thomas
A few hours ago I installed cacheman on my Windows '95 with update W'98 and..oh surprise...it is the best little tool in that matter, that I've crossed in almost 2 years I'm using my pc...before I sure have tried plenty of other tools, ..more or less efficient..but yours is far out. A friend of mine told me about it and sent me the CD rom from a german pc magazine EXTRA Freeware # 4:My set has never been as fast as after the installation of cacheman and there was no problem with the installation....congratulations!
Ray Irrthum
I wish I had found this superb little util 2 years ago. The cd-writer settings have boosted the performance of my P200mmx,32mb ram system to a very noticeable degree. I had a lot of problems with buffer underrun while burning cd-r`s, cacheman seems to have solved the problem instantly.
Well done. A postcard is on it`s way from Lanark, Scotland.
All the very best...

Cacheman has totally revitalized my PC!
Thanks a million!
Colin "Oscar" Smedley.
Just installed it this weekend. Brilliant, I have a PII266 with 128mb and it was running like a dog with 3 legs in Win98. Free memory was never above about 10mb, but now I have setup Cacheman for a power user I constantly have 50-70mb free - result everything runs much faster and applications zip open. Thanks very much - keep up the good work.

Recently I installed Cacheman v3.60. I'm pleased that the access to my hard drive has diminished markedly. Every so often my hard drive used to be accessed as if by an anti-virus scan, but that wasn't it. That's stopped since I installed Cacheman so I believe it must have been swapfile activity I was observing. Nice to have that annoyance eliminated,especially since my CPU is a desktop sitting right in front of me.

Richard Vopelak
I've tried a lot of programs that say they will speed up performance but most of them are just hype. I recently reformatted and my system was running very unstable. I restarted at least 20 times in 3 days. Windows kept using up all my memory and I only had a few programs open. White boxes would come up and say you are running dangerously low on resources and it would give me a choice of programs to close. I would try to close one and windows would lock up. This also happened when I tried to close out some programs that weren't responding using control alt delete and windows would lock up again. Now that I have Cacheman installed again everything is running great. I had Cacheman installed when I first got my computer and totally forgot about it after a few days. Thank you for a stable system once again!

Dear Mr. Thomas,
Downloaded a few days ago,it's been a great pleasure to install your CacheMan on my computer - before installing my RAM was just disappearing and nothing was left after a few working programs was loaded. It really works fine on my computer with any default settings.
Thank you so very much!
Yours sincerely
Thorben N°rgaard
I just downloaded your Cacheman freeware off the internet after seeing it on the Autopsy Report (via http://www.slaughterhouse.com). This is one great piece of software! Thank you, thank you, thank you. My free physical memory went from 80KB to 6100KB using the low memory setting! I'm going to experiment with the other settings.
Thanks again.
Matt Medena
Hi Thomas,
I think we have corresponded before, about some of your other software titles. I will not bore you with praise, you must have plenty!! You write software that is simple and useful, AND does not fill the hard drive with crap you never use a la Microsoft etc. Please keep me up to date with the stuff you are doing.
Thanx.
Regards,
John May
Thank you for the GREAT program you have written. No matter how much time you spent writing it, it can't be as much as the time I have spent trying to stop Win95 from swapping all the time. And I have 160 MB of RAM!!!VCACHE would regularly use 150 MB (155 MB once) for cache, while making the OS and programs do to swap. Now, with the settings I choose in Cacheman, I no longer use the swap file(except while editing large .jpgs).I never did understand the logic of VCACHE thinking that caching the swap file was faster than just releasing that memory to begin with. Now VCACHE doesn't have a choice in the matter. ;)
Jason Woods
I just want to say how thankful I am for Cacheman! I installed and tried it today and suddenly 9 months of problems with my computer are over. I've had trouble with the memory and I just couldn't figure out what to do to fix it. But a few days ago your Cacheman was in Softseek's newsletter and I thought I's give it a try. And it worked. Thank God! No, thank YOU!
From a happy Cacheman user,
Frode Kl°w.
This is just a really quick message to thank you for creating the wonderful 'cacheman'. I installed it a few days ago and am amazed at the results. I have claimed back about 4 - 10MB of memory, and as I use graphics appz such as photoshop an awful lot, this has dramatically speeded things up and just made life a lot easier.
There you go. Huge pat on the back. Well done!
Cary Charles
First of all, thanks for Cacheman. It improved the speed of my system drastically. I'm usually running Delphi, Word, Outlook Express, Internet Explorer etc at the same time and Cacheman improved response times tremendously. A postcard from Enschede, the Netherlands is on the way.
Arjen Broeze
I am a video producer, using Fast Electronics digital video products. There has always been considerable problem in switching between the editing software and the capture/output software in that system, seemingly because Windows 95/98 cannot manage the swap file mess it leaves behind. Among video editors, the controversy has gone on for some time about how to fix the problem, dealing with various placements and size of swap files,even turning it off. (then back on for various operations; a real pain!) When going between the two main applications, Premiere and DVManager, the system must be rebooted just to clean out the cache. Failing to do so will almost always result in a system shutdown. When you're busy trying to put maximum creative energy into a video production, I cannot possibly tell you how much of a problem the constant rebooting is!My first use of Cacheman would indicate that it helps, even perhaps solves that problem. If that is true, that would make whomever wrote this little jewel nothing short of a hero to all of us who edit video on PC's.

I just wanted to tell you that Cacheman 3.5 has made an incredible difference in my systems performance. I had almost given up using the Internet except in the early morning because it took SO..... long to do anything. This computer is an older Intel 100 with only 16 MB of memory. I really thought it was beyond hope! Although my new computer arrives next week, I do not think I'll junk this one as planned. Cacheman really made that much difference.
Thank you

Thanks for a great program. At last, a tool that made it easy to get a handle on the elusive MS cache monster. I've been through a variety of apps to "enhance" performance but none have been as effective and as common sense as Cacheman. And it doesn't eat resources!!
Bravo!!!

I just tried Cacheman 3.0 and I must say that it made a world of difference on my 233mhz 24mb computer! Now my computer has some pep in its step! I can't believe just a little 400kb download can do so much good! You program was easy to use too! I especially liked the simple way to set the disk cache ( I.E. Poweruser,Quake2 ) simple settings that a novice can even understand! My hard drive is a lot quieter now.
THANK YOU

I had the problem with runaway disk cache usage in w95. I have 256 MB and I'd have 200 eaten up caching junk I would never need again. Then I would swap constantly. I work with huge multi-image collages (100 - 150 MB). I now have much more free ram.

Thank you for your programs. As I was one of the fools that actually paid for Memturbo believing that it did something "more" than Cacheman. I ran both programs after a cold boot and discovered that Cacheman was actually more effective than the hyped Memturbo. As I'm under an extremely tight budget, I now regret paying the fee that Memturbo required. I also intend on installing your new ver 3.0 in about a minute - right after I uninstall MemTurbo. I appreciate the quality of your programs and depend upon generous developers like you for many utilities. I use all of your freeware and look forward to what you have coming up next. Your postcard will be arriving soon.
Thank you again...Merry Christmas from Everett, MA. USA

Dear Mr. Reimann,
This is a small note to say a BIG THANK YOU for Cacheman v.3.7 which I downloaded last night from the freeware segment of CNet. As reviewed therein, your program boosted my system's performance noticeably. I am a management consultant and consequently I frequently run Excel, PowerPoint and MS Project simultaneously. Also, the internet is my primary (and preferred, if you like) communication link with the outside world. So, as you can well imagine, my rather archaic system (I generally use a Toshiba laptop with measly 48Megs of RAM) is constantly overtaxed. After installing and running Cacheman under the power user setting, I find that my system performance is affording me the opportunity to postpone my projected investment in a second laptop. All thanks to you!!! can be sure of one thing, when I do get my new system, Cacheman is going to be one of the first utilities that I will be installing.
Again, thanks!!!!!
Sincerely,
Mana Guha
Two weeks ago, following Fred langa recommendation,I downloaded Cacheman for my Dell Dimension, PIII, 384MB SDRAM, 22.6 GB HD, running Win98 SE. Previous to Cacheman my System Resources had been 67% immediately after Restart and 63% after Internet browsing. Crashes and freezes are things of the past because every 4 weeks I spend 40 minutes with my $19. CD reinstalling Win98 SE, so as to clean files and tweak the system (better than Disk Cleanup).The Cacheman settings are Automatic for Beginners and the readings are 81% , 77% and the Disk Cache are min. 1024, max. 8192. The improvements in Resources have been great and my PC stays always fast.

Thomas,
CacheMan immediately proved what a hideous burden Vcache imposes on most Windows machines. Initially, with standard Windows settings ("let Microsoft decide") my 128mb RAM brought no great performance gains over the 64mb installed previously. After installing CacheMan, and with windows now snapping into place, I tinkered beyond the basic CacheMan settings and got 99mb RAM free. I did not expect this much of an improvement! This will change as my program mix moves over into heavy web graphics, but the benefit is enormous.
Appreciatively,
Brian Graham

Thanks a million for the fine cacheman program. I have had a lot of problems with my computer locking up, while working on webpages and jpg images,since I downloaded your program, I have not had that problem again. this is a great program.

First steps
If you launch Cacheman for the first time, you will see the Overview page of the Info section. The lowest and highest values are recorded only while Cacheman is running, so at this time they will not differ much from the current usage. Disk Cache and 16Bit resources information is available on Windows 95,98 and ME systems only.
You can switch between the 9 different Cacheman pages using the navigation bar located to the right of the Cacheman window.
Most pages have Help or Wizard buttons. Use them to learn more about Cacheman's functionality and change settings to fine-tune your system's performance.
If you do not have the time or knowledge to manipulate the settings you can of course try one of the predefined profiles. As registered user you can also ask support for performance related help.
Most settings require a system reboot for the changes to take effect. Cacheman saves your original system settings on first startup in a Profile named "Initial Settings". You can safely revert back to your original settings by loading this profile.
By default, Cacheman starts automatically with Windows and minimizes itself to the System tray. Double-click the icon in the tray to view the main window. You can disable the automatic launch feature by deselecting Load Cacheman on Windows startup in the Options section, if you do not need Cacheman's monitoring or Memory Recovery abilities.

This page displays several information values such as memory and paging file usage.
The lowest and highest values are recorded only while Cacheman is running, so at this time they will not differ much from the current usage. Disk Cache and 16-bit resources information is available on Windows 9x and ME systems only.
On Windows NT4/2000/XP Cacheman displays not only paging file usage, but also paging file allocation. This value represents the size of reserved paging file space for potential usage.
.topic 16
History Graph
The History Graph is useful if you want to watch an information value over a time period (e.g. when working with specific software).
Values available:
Physical memory - usage
Physical memory - free
Paging file - usage
Win 9x/Me only:
User resources - free

Logging
Logging is a function similar the History Graph, but instead of a visual display the values are written out to a log file. To start logging select the filename, enter the desired log values into the Logline edit field and turn on the Enabled checkbox.
Cacheman will replace the tags with the actual values - example:

Profiles
Save all settings into a profile before modifying them. This way you will always be able to revert to your old settings if anything goes wrong. The "Initial Settings" profile is created on the very first Cacheman launch on your PC. This profile cannot be deleted (for safety reasons). Profiles can be managed in the Settings section.
Cacheman offers 9 predefined Windows 95/98/ME profiles.
Desktop computer
Good profile for the average system.
Server
Self-explaining.
Games
Reduces background-activity to improve gaming performance.
CD Writer
This profile is recommended on buffer underrun problems.
Multimedia
Best profile for working with large multimedia files.
Multitasking
Use this profile if you switch frequently between several applications with high disk activity.
Low memory system
This is the best selection if you system is low on RAM.
Solve stability problems on >512MB system - method 1
Stability problems will be solved by adjusting the Disk Cache, works on most systems, but not on all!
Solve stability problems on >512MB system - method 2
The stability problems will be solved by limiting RAM to 512 MBytes.
Tip
Cacheman creates a directory named Profiles in its installation directory to store user profiles. Each profile consist of a file with the extension cpf. You can replicate your custom profile on any other computer. You simply need to copy the cpf file to the target computer and load the profile through Cacheman. This feature is particularly useful if you have a large network of computers and want to apply the same settings to all the computers or while sending it to your friends.
.topic 19
Disk Cache
Disk Cache is a part of RAM that acts as an intermediate buffer when data is read from and written to storage devices.
The Disk Cache driver stores the most recently accessed data in RAM. When a program needs to access new data, the operating system first checks to see if the data is in the cache before reading it from the disk. Because computers can access data from RAM much faster than from a storage device, disk caching can significantly increase performance.
What's the problem with the Windows 9x-ME Disk Cache?
The Virtual Memory Manager and the Disk Cache driver are two separate entities. The Virtual Memory Manager decides what portions of physical RAM can be swapped out to Paging file, while the Disk Cache driver determines what portions of disk files in use should be kept in memory to avoid slow disk operations. Unfortunately, the left hand doesn't know what the right hand is doing. The Disk Cache driver decides to cache data in RAM while the Virtual Memory Manager decides to swap out memory back to hard drive. In some cases, the two defeat each other, resulting in extremely bad system performance.
Cacheman will help you set the Disk Cache driver limits for your system and if necessary gain more free memory.
If you are not an expert user, launch the wizard for automatic settings or use one of the predefined profiles.
How can I test if my system has optimal Disk Cache settings?
A benchmarking program is not suitable for this purpose. A large Disk Cache speeds up most IO operations and the re-loading of applications by a significant amount, but on the other side if no free RAM is left a too large Disk Cache can decrease the general application performance by a huge amount due to increased paging file swapping.
The best method to test your settings is to create a worst-case scenario by loading several applications at the same time and work with them. If you encounter major slow downs (e.g. by processing large images in graphic software) try to reduce the Disk Cache to gain more free RAM. Registered Cacheman users can contact support to get performance related help.
Chunk Size
The Disk Cache is a single block of memory which is divided into chunks. The performance changes slightly with the Chunk Size. If it is too small, the data must occupy too many chunks and vice versa. An optimum size must be arrived at so that the Chunk Size is not too large and not too small. The default size of 512 Bytes is best. Most Windows versions ignore this setting anyway, so leave it at default.
Name & Path Cache
Path Cache specifies the size of the cache that the virtual file allocation table (VFAT) can use to save the locations of the most recently accessed directory paths. Name Cache stores the locations of the most recently accessed file names. This cache improves performance by reducing the number of times the file system must seek paths by searching the file allocation table. The memory is allocated out of general system heap.
A Wizard is available for novice users.
CDFS Cache
The CDFS Cache is separated from the Disk Cache because the performance characteristics of compact discs are different. This cache can be moved to swap file. When Windows retrieves data from a compact disc, it is still faster to read a record from the CDFS Cache even if it has been swapped out, because the hard drive access time is much faster compared to access time of the CDRom drive. DVDs primarily use the Universal Disk Format (UDF) for their file systems, this means the Disk Cache is responsible for most DVD-Discs, not the CDFS Cache!
A Wizard is available for novice users.
Icon Cache
Every executable file has an icon associated with it. Every time the shell displays a folder full of files it needs to obtain icons for each of those items. By saving icons that it has already retrieved into a cache, the shell is relieved of the need to constantly retrieve icons from executable files and icon libraries. This can make a vast difference to system performance, especially when accessing network drives.
After changing this setting you need to reboot at least 2 times until it becomes effective, but since it's not a critical setting Cacheman will not ask you on exit to reboot.
.topic 20
RAM
Recovery
This feature can recover RAM by swapping out unused parts (e.g. from inactive or crashed software) to hard disk. Instead of periodic recovery you can also use this feature on demand by right clicking the Tray Icon and launching the Recover memory now menu item or by enabling the Recovery memory now hotkey on the Options page.
Enabled
When turned on Cacheman will periodically try to recover memory.
Try to recover every xx minutes
This is the time amount between the recovery tries. This value depends greatly on your computer usage but should not be lower than 30 minutes.
If free memory is below
Cacheman will only perform the recovery process if the available memory is below this value. It makes no much sense to recover memory if a significant amount is still available. (The minimal limit value can be overridden in Cacheman.ini - add MaxBelow=xxx to [Recovery] section).
Memory amount
It's important to not choose a too large value here as this would free up data that could be needed within the next minutes by some applications. Only a good chosen amount ensures performance enhancements. Novice users should use the automatic setting for best results. Both the automatic setting and maximal user defined values are calculated according to your installed RAM amount. (The maximal manual value can be overridden in Cacheman.ini - add MaxAmount=xxx to [Recovery] section).
Example
Try to recover every 40 minutes
Memory below value: 20 MBytes
Memory amount value: 10 MBytes
Cacheman will contantly check if memory is below 20 MBytes and recover every 40 minutes. Assuming 15 MBytes were available Cacheman will try to recover 10 MBytes. On success you should get 25 MBytes free RAM.
Do not recover on high CPU usage
This setting is highly recommended. Cacheman will not try to recover memory when your CPU is doing some heavy work (e.g. when your are playing a game). If Cacheman detects high CPU Usage it will postpone the recovery.
Do not recover on high disk activity
This setting is similar to the CPU Usage setting, but it measures high hard disk activity instead. Highly recommended. If Cacheman detects high disk activity it will postpone the recovery.
Recover on startup
Cacheman will try to recover memory immediately after program start.
Change Tray Icon when recovering
If checked, the Tray Icon will change when Cacheman is performing a Memory recovery operation.
Extreme recovery mode
If you turn on this setting Cacheman will try to recover memory in 2 steps instead of 1. It should free more RAM, but the recovery process will be slower, so we do not recommend this setting for the average user!
Status
Cacheman will output some status information into this box like the amount of successfully recovered memory after a recovery try.
Optimization
Unload DLLs from memory
Windows automatically unloads DLLs when the usage count is zero, but only after the DLLs have not been used for a period of time. This inactive period might be unacceptably long at times and cause performance slow downs on low memory systems. Enable this option to disable Windows holding the DLLs in memory.
Conservative Swap File Usage
The PageFile Call Async Manager feature in Windows 98-ME allows the Memory Manager to asynchronously write out swap file buffers during VFAT idle times. This results in more free memory, but causes permanent HD activity even if no application is in memory. To disable this HD activity you have to turn Conservative swap file usage on. This is recommended if you have at least 256 MBytes of RAM and are using Cacheman's Memory Recovery feature.
Limit available RAM to 512 MBytes
This setting limits total available RAM to 512 MBytes. Windows 95,98 and ME does officially support 512 MBytes at all, with more installed RAM it can become very unstable. If you are using multiple operating systems on your computer and have due to this usage more than 512 MBytes installed it is recommended to check this setting. Windows 95,98 or ME gets no real advantages of more than 512 MBytes anyway.

Disk
VFAT Contiguous Allocation Size
Fragmentation occurs over time, as programs read from and write to the hard disk. Eventually, files must be stored in noncontiguous sectors on a disk. Fragmentation does not affect the validity of the information, but it takes much longer for the computer to read and write fragmented files. Under MS-DOS, the file system began allocating the first available space found on the disk, which ensured a great deal of disk fragmentation and related performance problems. By default under Windows 9x-ME, the file system first tries to allocate space in the first contiguous 512 KBytes to prevent extreme fragmentation. Increasing this value can result in even less fragmentation and improved performance.
Read-Ahead Threshold
Read-Ahead Threshold is the amount of additional bytes that will be read when a application reads data in sequence. It is meant to improve read performance by anticipating the next read. This works in many cases, unfortunately the performance will decrease if more than one application accesses the hard drive at the same time.
IO Page Buffers
This setting specifies the number of page buffers used to store asynchronous read and write pages when accessing the hard drive. This setting is used only if you are using 32-Bit Disk Access and a permanent swap file. Increasing this value can improve Windows performance.
Miscellaneous
Hung App Timeout
Windows waits by default a long time to finally acknowledge that a particular program is "Not responding", and only after that allowing you to shut it down by clicking the End Task button.
Wait to Kill App Timeout
This value sets the timeout until Windows shuts down/restarts, while trying to exit all open programs.
Show Menu Delay
Decreasing this value makes the Start Menu cascading menus appear more quickly.

Disk Cache
Windows NT4/2000/XP has a much better Disk Cache handling as Windows 95-ME. Windows NT4/2000/XP uses certain criteria to decide how to prioritize memory usage between the Disk Cache and applications. This dynamic allocation process is a continual juggling act. Four configuration presets are available.
Minimize memory used
This setting minimizes the amount of memory used for the Disk Cache in order to maximize the amount of memory available for applications. This is the default setting for Windows NT Workstation and Windows 2000 Professional.
Balance
This setting instructs Windows to give the Disk Cache and applications the same priority.
Maximize throughput for file sharing
The Disk Cache gets a higher priority with this preset. It should be the best for file servers and workstations with very high I/O activity.
Maximize throughput for network applications
This setting instructs Windows to give applications higher priority. It should be the best preset for application servers.
Icon Cache
Every executable file has an icon associated with it. Every time the shell displays a folder full of files it needs to obtain icons for each of those items. By saving icons that it has already retrieved into a cache, the shell is relieved of the need to constantly retrieve icons from executable files and icon libraries.

Disable executive paging
Parts of system code and device drivers can be swapped out to paging file when the system needs more RAM. The system slows down when it needs that code or drivers since it must load them from the paging file. Windows stops while the required code is swapped in or out of RAM dependent on very long hard drive access times. If you have more than sufficient RAM, disabling Executive paging should improve performance.
Unload DLLs from memory
Windows automatically unloads DLLs when the usage count is zero, but only after the DLLs have not been used for a period of time. This inactive period might be unacceptably long at times and cause performance slow downs on low memory systems. Enable this option to disable Windows holding the DLLs in memory.

Disk
IO Page Lock Limit
If your system is very IO intensive you can increase the amount of memory that can be locked for IO operations when data is read from or written to the hard disks. When this value is 0, the system uses the default (512 Kbytes). Raising this value can give you a significant performance boost.
Disable NTFS last access update
By enabling this option, NT Filesystem will not record the last time a file was accessed. This can speed up disk operations if applications write many small files very frequently.
Miscellaneous
Hung App Timeout
Windows waits by default a long time to finally acknowledge that a particular program is "Not responding", and only after that allowing you to shut it down by clicking the End Task button.

Show Menu Delay
Decreasing this value makes the Start Menu cascading menus appear more quickly.

Disabling Cacheman
How can I restore my original (pre-Cacheman) settings?
On first launch Cacheman has saved all your settings into a profile called "Initial Settings" (this profile cannot be deleted within Cacheman). To restore your original settings simply load this profile, save the settings (File Menu) and reboot.
On uninstallation Cacheman will automatically load the "Initial Settings" profile to restore your original settings!
How to disable Cacheman without uninstalling it?
Go to the..

Does Cacheman work on Windows NT4/2000/XP?
Yes, most settings are designed for Windows 9x-ME, but Cacheman offers even some NT4/2000/XP only settings.
What are GDI / User resources?
System resources are areas of memory that are used by the input manager (USER) and the graphic display interface manager (GDI) for keeping track of all of the windows that are open in a session and for drawing objects on the screen.
The Graphics Device Interface (GDI) is the graphical system that manages what appears on the screen. It also provides graphics support for printers and other output devices. It draws graphic primitives, manipulates bitmaps, and interacts with device-independent graphics drivers, including those for display and printer output device drivers.
The User component manages input from the keyboard, mouse, and other input devices and output to the user interface (windows, icons, menus, and so on). It also manages interaction with the sound driver, timer, and communications ports. Windows 98/ME uses an asynchronous input model for all input to the system and applications. As the various input devices generate interrupts, the interrupt handler converts these interrupts to messages and sends the messages to a raw input thread area, which in turn passes each message to the appropriate message queue. Although each Win32-based thread can have its own message queue, all Win16-based applications share a common one.
The size of each heap is fixed.
16-bit User heap (64K)
32-bit User window heap (2MB)
32-bit User menu heap (2MB)
16-bit GDI heap (64K)
32-bit GDI heap (2MB)
