https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D265337 Bug ID: 265337 Summary: 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. Product: Base System Version: 13.1-RELEASE Hardware: amd64 OS: Any Status: New Severity: Affects Some People Priority: --- Component: kern Assignee: bugs@FreeBSD.org Reporter: wocson@gmail.com FreeBSD wcsn 13.1-RELEASE FreeBSD 13.1-RELEASE releng/13.1-n250148-fc952ac2= 212 GENERIC amd64 CPU: AMD Ryzen 5 3600 6-Core Processor (3600.10-MHz K8-class CPU) vendor =3D 'Advanced Micro Devices, Inc. [AMD/ATI]' device =3D 'Lexa PRO [Radeon 540/540X/550/550X / RX 540X/550/550X]' Have last KDE Plasma, amdgpu, mesa, drm. 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. Accidentally came across a mention of the key: kern.sched.steal_thresh. I write to sysctl.conf: kern.sched.steal_thresh=3D1 machdep.idle=3Dmwait Setting it to 0 or 1 (default is 2) sysctl kern.sched.steal_thresh=3D0(1) completely eliminated all microphryses. --=20 You are receiving this mail because: You are the assignee for the bug.=
