  I forgot to mention that I'm running redhat-5.2 with kernel 2.2.1. Which
  btw includes the latest driver (version H).

ok..

i had similar problems with a network card. things like telnet,
ftp, web worked fine, no bother. but nfs was extremely slow.

turned out to be a slight problem with my cabling. (a badly wired
jack in fact). which was causing slight packet loss. ftp, telnet,
etc. could cope cause they were using TCP - reliable. But it was
the kiss of death for unreliable UDP based NFS.

Quake, i believe, uses UDP.

run ifconfig and have a look at the {tx,rx}errors fields.

also, things like serial ports, and IDE drives that havn't been
setup properly with hdparm, can raise a lot of interrupts, and
delay other drivers response to their own interrupts, eg perhaps
causing tx/rx errors in a nic. (esp with 100BaseT).

see man hdparm.

(try hdparm -u1 /dev/hd?)

hth.

regards,

Paul.
