HTT should be disabled to get better performance metrics on a server as it can inflate values to be off by alot. When you turn it off you might see about a 2 percent drop in some performance but it's worth the tradeoff in my opinion. Go out to Intel's web site's "developer" section, and look for "SMT". There's alot of literature about performance measurements.

Any suggestions would be very helpful! I'd contest that you dont have four CPU's. You have two real ones and two "fake" HT impressions of CPUs. I'm guessing that with two instances of HLDS with AMX and heavy pingboost with high FPS, you are using almost all of the real processors, yet your OS is counting the fake ones towards the overall load (thus in effect making it seem low). When you fire up the third instance, this is asking more than the CPU's can provide and thus you see the performance issues. I'd bet that you'd see almost identical behaviour with HT off as on.
