Just as a test for RELENG_6, could you try setting kern.hz="100" in your loader.conf, and repeating your tests? I'm just guessing, but maybe the higher interrupt rate is a bit too much for an old Celeron... :) Cheers, Dimitry _______________________________________________ freebsd-stable@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to "[EMAIL PROTECTED]"
