If you have a lot of small transactions that need seeks they'll kill performance (try running "find /" - you'll get ~500 kB/s rate and 100% busy disks). _______________________________________________ [email protected] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-performance To unsubscribe, send any mail to "[EMAIL PROTECTED]"
