I just want to point out one drawback to "leave it on recommended" for # of threads.

i have a 4core cput wiht intel's multi-(hyper-?)threading -- whichiver the tm is. 4 physical cores and a little gimmick that uses the 'math' portion of the chip as it's own 'core', in layman's as best i know.

anyway... in this situation, recommended uses "8" which slows down everything significantly even compard to just "1" thread, at least with my pc.

if i use "4", everything is much faster than "1" thread.

so, it's better to say set it to the # of physical cores. unless this turns out to be a localized issue.

This type of cpu feature is generally defaulted "on" in the bios/uefi. so, 'recommended' will use 2x physical cores for anyone with a similar architecture (gimmick that makes a chip "double" physical cores - AMD has this too) unless they changed this bios controlled feature, which isn't likely.
