[Bug 265337] There were annoying microfreezes lasting 0.1-0.2 sec at any work: scrolling through texts, watching videos, playing audio, even moving the window across the screen gave such delays.

--- Comment #1 from Mark Johnston <markj@FreeBSD.org> ---
If you are willing to test, please try building and running a kernel from the
main branch (no need to replace anything else) with default settings.  A few
race conditions in the scheduler were fixed, which could result in CPUs going
idle with work to do.  In some sense, setting steal_thresh=1 can work around
these problems.

> kern.sched.steal_thresh=1
> machdep.idle=mwait

Are both settings needed?
