I'm sure those old disks have slow IO. You might want to look at a
hardware raid card (Compaq Smartarray if they will work outside of a
Compaq), and then some 10k RPM SCSI disks.

Exactly, modern disks will buy you quite a bit.

We have two PIII-600 dual compaq 1850R's, and they are quite zippy.

Yea, this is probably your biggest load? All the perl script virus scanner
glue. You might be able to find optimizations, or use two boxes - one to
run crufty glued-together virus scanning / mime removing / spam nuking
programs, and one to do everything else.

That all shouldn't take much load at all.

As uncool as they are, x86 is fast. I/O is a big thing, and proper disks
for unix boxes that move are expensive. I wish the floor would drop on
SCSI disks but noooo.

One of those ones that can do embrodering? Those seem cool.
