Fragmented, shmagmented: RAID 5's write performance is horrendous in all cases. It should never be used on a mail server. Best practices dictate RAID 1, RAID 0+1 if affordable, with as many drive spindles as possible dedicated to each mail server function (spool, web spool, logs, mailboxes, swap, system, etc.). You've done about the opposite, choosing the slowest RAID and running all functions off the same array. > http://bandwidthplace.com/speedtest shows between 5.0 and 3.7 > megabits per second. Between you and the Internet? Irrelevant. On your LAN? Horrible! If you're running ODBC over this kind of connection, that'll ruin some components' performance on its own. > IMail is configured to use an external database (done before I got my > hands on the machine.) After reconfiguring as much as possible as above, rebenchmark performance and get your hands in there and change it to the IMail native database if necessary.
