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.

Yes, this could count as "understand enough about your machine"
Although in general, it also depends on how much else you run on your machine at the same time. For example, if you're not running anything else, then I would expect that a 4 core/hyperthreaded box should still run ever so slightly faster with 8 threads than with 4. However, if you're running a bunch of other stuff too, then the 8 threads can slow it down enough to cause issues.
So yes, if you don't feel that threading helps much, then try half the recommended value.
