The sysctl is visib= le as kern.ipc.umtx_min_timeout. I set it to 10ms (10000000ns) by issuing "sys= ctl kern.ipc.umtx_min_timeout=3D10000000" but unfortunately there doesn't seem = to be any effect.

No complaints here. Having it per-process is much appreciated. May I ask if it will be included in an update for 13.2-RELEASE? Or will it = wait until 14.0? --=20 You are receiving this mail because: You are the assignee for the bug.=
