LXOPT
LXOPT is an OS/2 software development tool. By working set tuning EXE/DLL
files LXOPT will typically halve the amount of memory required to store
application code. The instruction stream is also processed to ensure maximum
CPU instruction cache efficiency and a PRELOAD option allows the use of this
Preload Utility which transfers the application to the swapfile at machine
start-up.
If you are interested in LXOPT please contact your local development tools
supplier. A fully functional demonstration version is available as
LXOPTnnn.ZIP (where nnn is the current version number) at numerous internet ftp
sites including ftp://hobbes.nmsu.edu in the os2/demos directory.

ΓòÉΓòÉΓòÉ 3. Welcome to the Preload Utility! ΓòÉΓòÉΓòÉ
Welcome to the Preload Utility!
This utility takes specially prepared software, processes it and stores the
result in the OS/2 swap file. Once in the swap file these applications may be
loaded much more efficiently. By preloading software in this way you can
choose to devote more of your computers resources to your favorite
applications. Preloaded applications will startup quicker and perform much
better in low memory conditions.
How Is It Used?
Preload is normally used at machine start-up by issuing requests to load
specific applications. These requests are normally placed in startup.cmd which
is executed every time OS/2 starts. Preload is particularly effective where
applications need to be loaded from a busy network. See the Using PRELOAD
section for more details.
What Can I Use It On?
The utility will only work with the EXE and DLL files of specially prepared
applications. The developers of these applications have already used the
latest technology to ensure that their software consumes the least possible
amount of your computers memory. This reduced memory use not only makes these
applications faster, it frees more of your computers memory for use with other
applications. By providing you with this utility the developers have given you
the option to further increase run-time performance.
Check the documentation of your application(s) to see if the developers provide
any special advice on the use of this utility.
Should I Use It On Everything?
Each application you preload will add extra time to machine startup when it is
preloaded. It also increases the size of your swap file. It is up to you to
choose which applications you are willing to devote these resources in order to
increase run-time performance.
As PRELOAD increases the use of your swap file you may need to take extra care
that it does not run out of disk space. See the description of the /M option
for more details.
Network Issues
If you are a user on a managed network please inform the network manager of
your use of this software. Preloading code alters the balance of the work load
on your machine. Network load will increase at machine startup but will be
reduced dramatically while running preloaded applications. Using PRELOAD also
increases the desirability of larger local hard drives.
