https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D236096 Bug ID: 236096 Summary: top shows WCPU numbers greater than 100 percent when using SCHED_BSD Product: Base System Version: 12.0-STABLE Hardware: amd64 OS: Any Status: New Severity: Affects Some People Priority: --- Component: bin Assignee: bugs@FreeBSD.org Reporter: ian@FreeBSD.org After switching from SCHED_ULE to SCHED_4BSD I immediately noticed that top displays wildly inaccurate numbers for WCPU. If you switch the display to un-weighted CPU the numbers are mostly right (rarely you'll see a 101% type number).
