kern.timecounter.tick: 1 kern.timecounter.choice: TSC-low(1000) i8254(0) HPET(950) ACPI-fast(900) dummy(-1000000) kern.timecounter.hardware: ACPI-fast kern.timecounter.stepwarnings: 0 switching the machine from TSC_low to ACPI-fast fixes the problem. in 8.x it used to default to ACPI but I used to switch it to "TSC" to get better performance. I wonder why TSC-low is now bad to use.. maybe the TSCs are not as well sychronised as they were in 8.x? maybe the pthreads code didn't get the memo about changing timers? _______________________________________________ freebsd-stable@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to "freebsd-stable-unsubscribe@freebsd.org"
