That machine has the 2144UW on it. I put the max for that card (64mb EDO)
cache on it.

I'd do some solid performance testing on that card before upgrading to 256
megs of cache. (I didn't even know that model would take that amount) It
certainly sounds like overkill to me. I went with the 64 megs only because
I had a cheap source for the RAM. It is certainly more than we needed at
the time...

Because of the filesystem performance problems with linux's ext2
filesystem we opted to go FreeBSD instead.
