Sorry to drag this up again :) I would check myself, but I don't have access to a HT enabled machine with FreeBSD on it anymore to check the now-default setting of this sysctl. The last entry in UPDATING records that machdep.hlt_logical_cpus is 1, stopping user processes from using the logical CPUs. Is this still the case? I never knew about that to tweak it. I know, I should have read UPDATING. If that is still 1 as default, that might explain my 50% performance loss on FreeBSD. -- Chris
