https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=270785 --- Comment #14 from bllcha013@myuct.ac.za --- Thank you, it works now. Setting kern.ipc.umtx_min_timeout to 10000000 (10ms) gives nice low CPU usage, and the CPU is spending much more time in low-power C-states. I'll keep an eye on it for a while more but for now it seems perfect. I really appreciate this patch, and I'm sure others will find this very helpful. May I ask if this patch will be included in an update or patch to FreeBSD? -- You are receiving this mail because: You are the assignee for the bug.
