Settings Page

On this page you can optimize your system settings. The page is disabled on Windows NT4/2000. An easy way to optimize is to use one of the presets from the Preset menu.

You can change the values by clicking on the calculator symbol in the adjacent edit box. Alternatively, type in the desired values in the edit boxes.

Minimal Disk Cache

The Disk Cache size will not go below this value.

Maximal Disk Cache

The Disk Cache size will not rise above this value.

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 for most purposes.

Read-ahead Threshold

This slider changes 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.

Name and 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. This cache improves performance by reducing the number of times the file system must seek paths by searching the file allocation table. Name Cache stores the locations of the most recently accessed file names.

Conservative Swap File Usage

By enabling this checkbox you can disable the PageFile Call Async Manager feature that allows the Memory Manager to asynchronously write out swap file buffers during VFAT idle times. This settings reduces the Virtual Memory swapping, but is only recommended if you have a large amount of Free Memory.

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.
