Hi everyone, I'm trying to use kqueue with EVFILT_TIMER to create an interval timer. However, I'm getting very unreliable results.
The code for a test case is at: http://pastebin.com/ratK0AXL I'm finding that regardless of the number of ticks I wait for, it takes around 50% longer than it should. For a 20ms interval, 200 ticks takes 6s not 4s, 2000 takes 60s not 40s. I am running FreeBSD within a virtualbox VM (Windows host, no load) so I know timing may not be as reliable as if I was on the bare metal, but this still much higher than expected. -Steve _______________________________________________ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "freebsd-questions-unsubscr...@freebsd.org"
