I once read about a piece of software sold by Maxisoft that allocated memory to be used as a disk cache. Has anyone tried this or any similar program, and if so, how much is Disk I/O performance improved for generic tasks ( such as executing CLI stuff, compiling, etc.) ? --Craig Hughes [Disclaimer: I admit to everything... Sue me !]

Disk caching comes standard with 1.2. Simply use the AddBuffers command to tell the system how many buffers to use for each disk drive. I've heard people say that they've used 1500 buffers and such with expansion memory, but I've found that using 50 or 100 is really sufficient. With this many buffers, the disks are rarely accessed whenever you run the same program twice or get the same directory twice. Gary
