Increase the Disk Cache Size to Improve Performance In Heavy Disk Use Applications
The disk cache is used to hold the most recently-accessed information from the hard disk. If you are using your PC for work that is hard-disk-intensive, you may benefit from increasing the size of your disk cache.
The default operation of the disk cache under Windows 95 is to "suck up" large amounts of available memory for the cache and resize it accordingly. If you have left this default behavior in place, there isn't really that much for you to do, since Windows is managing the cache itself. However, if you set a fixed disk cache size then you need only increase the size of the cache by editing the SYSTEM.INI file and changing the numbers in the "[vcache]" section.
Under Windows 3.x, the disk cache is controlled by SmartDrive, which is loaded from DOS before Windows 3.x is invoked. The size of the cache maintained by SmartDrive is determined by the parameters given to the program. Type "SMARTDRV /?" or "HELP SMARTDRV" at a DOS prompt for more specific information.
