That "patch" would make a good tunable candidate either for the multiplier or the actual buffer value. -- othermark atkin901 at nospam dot yahoo dot com (!wired)?(coffee++):(wired); _______________________________________________ freebsd-stable@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to "[EMAIL PROTECTED]"
