6. Disk Drive Performance Hacks > 66. Speed Up Windows with VCACHE

Speed Up Windows with VCACHE

If you absolutely must stick with Windows 9x or Me the least you can do is give your system this free performance-boosting tweak to your Windows disk cache.

The Windows operating system creates and maintains its own read-ahead disk-caching service to help speed things up, but Windows itself does not give you any direct control over VCACHE. Instead, you have to dig into the C:\WINDOWS\SYSTEM.INI file with a text editor to set the caching service to your liking.

When setting a value for disk caching, you have to balance the amount of RAM to be used for programs and data with the RAM set aside for disk caching. If a lot of RAM is assigned to disk caching, that leaves less for programs and data and Windows will use the swapfile more, which will slow things down. If you assign too little RAM for disk caching, disk operations may be a bit slower but Windows may use the swapfile less, thus keeping performance up a bit.
