the only thing HT might help is offloading other processes (like nic/kernel/ide/scsi reqs). The thing to remember is you only have two processors to use. HT helps you use the resources on them more effectively, but doesn't magically make them a proper SMP solution.

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. Ian mu wrote:
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.
