I agree.  I'd look at what NIC's are being used, and get rid of
anything ISA.  All PCI Intels or 3Coms should make it a closer
matchup.

There was recently somebody on the list that I suggested switch to
Intels, and he posted back later saying it fixed the issue he was
having, and also dropped CPU utilization from ~35% to ~7% on a PII
233.  (I don't remember the exact details, but NIC's can make that big
of a difference)
