I've been using a 192K disk cache on a 2 meg Mac running under
MultiFinder for over a year without a single problem attributable to
it. Prior to running MultiFinder I had it set to 1 meg, again without
problem.

The "optimal" size of the cache depends on what operating system
environment you run and what kinds of applications you use.
Determining the exact size that's right for you is pretty much a
matter of trial and error experimentation.
