a) Check disk connectivity and health b) Don't let your mailserver swap: - add memory and/or - divide load over multiple machine c) Limit disk io if you cannot stop occasional swaps: - mailstore on different physical disk then queue, no swap on this disk - memory disk for logs - switch to Maildir if using mbox Mailservers are particularly bad for swapping as every new request will 100% result in one disk write (the logfile) and possible more (header file, queue body). -- Mel _______________________________________________ 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"
