I was wondering if there are any rules of thumb out there concerning disk cache? Is the default more than enoungh or can one enhance performance at another seting. If another setting is better what would be recomended for someone with 32MB, 64MB, 128MB, 256MB, 320MB,...?

Using the default is fine. The default will increase when additional memory is installed in a machine, but there really isn't any benefit passed whatever the default disk cache is with 64 megs installed. I believe the rule is 32k of cache for each 8 megs of RAM installed in the system.

I just got the new 4th Edition of "Sad Macs, Bombs, and other Disasters" by, Ted Landau, today. He say's "Recent versions of the Mac OS have become quite smart about deciding the optimal size for the disk cache. Using the "Default" setting is usually fine.

8 megs with 128.
4 megs with any less.
16 megs with 320 megs or over.
