If you have allot of users and allot of mail you are going to have allotof I/O. No way around that, regardless of the server. Cyrus' indexesheaders better now, so that might help. But you still need adequatethrough-put. I've found that /var/lib/imap (meta-data) needs fast I/Obut /var/spool/imap (message store) doesn't due too bad tossed onto aSAN or slower disks. ----Cyrus Home Page: http://cyrusimap.web.cmu.edu/Cyrus Wiki/FAQ: http://cyrusimap.web.cmu.edu/twikiList Archives/Info: http://asg.web.cmu.edu/cyrus/mailing-list.html
