https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D241958 Tom Jones <thj@FreeBSD.org> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |thj@FreeBSD.org --- Comment #5 from Tom Jones <thj@FreeBSD.org> --- I think I can reproduce this on 12-stable (r362275) With options TCPHPTS, I see a consistent interrupt load on a bhyve vm on a = 12.1 host. CPU: 0.0% user, 0.0% nice, 0.0% system, 8.0% interrupt, 91.9% idle Without TCPHPTS the vm is almost completely idle and there is no interrupt load. --=20 You are receiving this mail because: You are on the CC list for the bug.=
