HT is not going to help in this environment. Turning it off is
not going to hurt performance. It will more than likely help a
bit since the kernel scheduler is not having to juggle two fake
cpu's and can concentrate on the two real cpus.

Urgh don't turn off HT with 3 servers, probably the worst thing you
can do (with 2 or 2 process is fine without). Thing to remember is
there's no accurate way of reading HT cpu usage, so they may look a
bit skewed, but check other things like fps and you should fine you'll
get more.

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.
