https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D225535 --- Comment #20 from Aleksander Derevianko <aeder@list.ru> --- Now with em0 devices: A1 computer: root@fspa1:~/clock/new_res # grep times periodic_em0.txt | awk '{print $3 "= " $4 " " $6 " " $8 " " $10;}' | sort | uniq -c 11256 send_sync 0 0 0 0 10968 send_sync 0 0 0 1 234 send_sync 0 1 0 0 1 send_sync 0 1 0 1 A2 computer: root@fspa2:~/clock/new_res # grep times periodic_em0.txt | awk '{print $3 "= " $4 " " $6 " " $8 " " $10 ;}' | sort | uniq -c 18284 send_sync 0 0 0 0 2490 send_sync 0 0 0 1 1704 send_sync 0 1 0 0 Current results seems just fine. I think, rare delays for 230ms in previous tests is actually Realtec card problems. It's cheap TP-Link TG-3468 device,= so if it will continue to work fine with build-in em0 I will consider problem solved.=20 Actual solutions seems to be=20 kern.eventtimer.periodic=3D1 I will try to set only=20 kern.eventtimer.periodic=3D1=20 and=20 kern.timecounter.alloweddeviation=3D0=20 parameters, leaving everything else to system defaults. --=20 You are receiving this mail because: You are the assignee for the bug.=
