One thing to consider... I've seen a case or two where pgbench running
on windows with HyperThreading enabled was actually faster than with it
turned off. (General experience has been that HT hurts PostgreSQL). I
suspect that the windows kernel may have features that allow it to
better utilize HT than linux.
Of course if you don't have HT... it doesn't matter. :)
