virtualpaggingfile

This tweak can increase the amount of RAM significantly used on your
computer. What this tweak actually does is it uses your hard-drive
disk-space to emulate RAM. This is called caching, or in Microsoft
terms - The Virtual Paging File Size.

1.) Go into Control Panel and into Performance and Maintenance
2.) Get into System
3.) Click the Advanced Tab
4.) In the Performance Frame, click on Settings
5.) Once in Settings click on the Advanced Tab
6.) Now under Virutal Memory click on Change
7.) Here you can set your RAM value. The recommended increase you
should make should be achieved by multiplying your RAM by 1.5. This
is already done if you have a System Managed file size. I like to
increase it by 1/5 of my actual hard-drive space. This will drastically
increase performance, because the system will now have a pool of cache
to retrieve memory from.

Happy Tweaking!
