That's good stuff to know for the day when I get to play with a box
that has more than2 actual cores. Regarding turning off
hyperthreading, I assume it's known which pairs of CPU's are
actually the same core? Maybe you could see if there's any
performance difference running it on 1, 3, 5, and 7 versus 1, 2, 3,
and 4 (assuming that 1 and 2 are core the first core, 2 and 3 are
the second, etc). <br>
