Not that this will help much but Gary's post had me wanting to do a little
looking at stuff myself.
I threw up a quick server.. box is an AthlonXP 2800, 2gb DDR400 Running FC4
cat /proc/version = Linux version 2.6.19-rc1KC2 ([EMAIL PROTECTED]) (gcc
version 4.0.2 20051125 (Red Hat 4.0.2-8)) #2 Sun Oct 8 01:35:36 PDT 2006
The KC2 at the end of the kernel is my own stuff for testing tracking.
The server I ran was a tick 100 css lan server with -nomaster set map was
dust2. I connected with my client..
strace output..

nanosleep is called often, and it's very expensive if you have HZ => 1000
sendto is normal :)
If you want to spring some more stuff, try and load the server with
clients then strace it again. I'm curious to see the results.
