Dear all,

I got 5 computers with two XEON 5520 and 24G memory. I find the
Hyper-Threading is switched on by default. I wonder if QE could benefit from
Hyper-Threading Tech. of Xeon CPUs?
Should I switch it off and trigger one process for each core to promote the
QE performance?
Or remain the Hyper-Threading on and trigger two processes for each core?
