Unfortunately, this didn't show anything significant. But I've played around a little and built a kernel without WITNESS and friends, but with "options ADAPTIVE_MUTEXES". Now the box is up for almost five hours and is still running, which really surprised us. :-) Throughput is ok, but the limiting factor currently seems to be disk I/O. It's a pity that ciss(4) isn't more performant right now. Anyway, we hope the box stays up and we'll keep monitoring that. regards, le -- Lukas Ertl eMail: [EMAIL PROTECTED] UNIX Systemadministrator Tel.: (+43 1) 4277-14073 Vienna University Computer Center Fax.: (+43 1) 4277-9140 University of Vienna http://mailbox.univie.ac.at/~le/ _______________________________________________ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-current To unsubscribe, send any mail to "[EMAIL PROTECTED]"
