None of these should be an issue, but:

For some reason with the default value of 2, I'm seeing weird stuttering in
youtube
videos, games, etc. on a 5950X system. 1 (or 0, IIRC) works fine.
yes, finally... Using a Ryzen 1700, Asrock AB350 Pro4 and Radeon RX460 and got
that
awful micro stuttering all the time; not only under FreeBSD 13.0-ALPHA3 now,
but also
under FreeBSD 12-STABLE in the past.
Occurences were during listening to music using MPV (one-second-*krk*-loops);
watching
YouTube videos (video hangs for a second but audio continues) and often simply
during
mouse movements where even MouseKeyPress- and MouseKeyRelease-events just
didn't reach
the system at all.
Setting
kern.sched.steal_thresh=0
eliminates these micro stutterings in the whole system.
I also would really, really like to know the reason why this parameter has such
an
impact...
Many thanks for the hint and BR,
Nils
