You may want to look at your config and your kernel settings.  Ive got 
one or two DC servers on single proc boxes (dedicated Athlon 1700+) and 
the 30 players runs slightly under 40% cpu when full, the 42 player runs 
at around 50% cpu when full. You should be getting alot more from your 
server then you are.
