I guess the default as it is not set anywhere (in linux it can be changed only during boot time i think) Do you have idea how can I see the current timecounter on linux ? :) This is what I found in dmesg: time.c: Using 3.579545 MHz PM timer. Calibrating delay using timer specific routine.. 4416.34 BogoMIPS (lpj=2208170) Calibrating delay using timer specific routine.. 4409.37 BogoMIPS (lpj=2204688) Using local APIC timer interrupts. Detected 12.528 MHz APIC timer. Disabling vsyscall due to use of PM timer I guess this means that ACPI timer or PM Timer is used? :) > >> Here are the max speeds I can reach with different counters (on the >> test server): >> >> i8254 - 3.660 MB/s >> ACPI-fast - 7.137 MB/s >> TSC - 12.519 MB/s >> dummy - 12.366 MB/s > > Kris > _______________________________________________ > freebsd-hackers@freebsd.org mailing list > http://lists.freebsd.org/mailman/listinfo/freebsd-hackers > To unsubscribe, send any mail to > "freebsd-hackers-unsubscribe@freebsd.org" -- Best Wishes, Stefan Lambrev ICQ# 24134177
