If you just want a relative count (i.e., not absolute time) and if your machine's aren't going to be in sleep modes, you could use the RDTSC instruction directly. -- FreeBSD Volunteer, http://people.freebsd.org/~jkoshy _______________________________________________ freebsd-hackers@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-hackers To unsubscribe, send any mail to "[EMAIL PROTECTED]"
