Thank you for your thoughtful and well spoken answers to my inquiries.

So what exactly is the point of the AFS cache file then, I mean if the info 
is going to be in the Windows swap file anyway?

Ok yea, my experiment this morning confirmed this observation.

All the machines have 256 Meg physical memory with 384 Meg page initial, 
768 Meg page max.
The AFS cache file is set to 256 Meg.

This was after I had stopped the AFS service, cleared the cache, started 
AFS up, and copied a 640 Meg file from AFS to the local drive.

I suppose I can set a smaller AFS cache, but according to you there should 
be some kind of sweet point where too low does little good, and too high is 
diminished return, and worse a slow machine.  And this uglyness is 
dependent on the amount of RAM a machine has.
