TF2 CPU Usage on FreeBSD

[RIFGenesis]

Hey guys

I am currently running a 24 slot 66 tick TF2 server on a dual CPU, dual core Opteron 275 (2.2Ghz) with 4GB ram on FreeBSD 7. I'm finding that the cpu usage is quite high when the server is full and generally sits around 75% of a core. Can anyone with a similar spec machine tell me if this is this normal? Other FPS games I am hosting use nowhere near this even with more players.

i had a similar machine w/8G ram, you're about 10% higher in cpu than mine was. it has since been replaced with dual xeon 5160 and usage has dropped a bit with same number of slots.
