Mac OS X 10.5.8
Two mirrored 7200rpm sata drives.
dbox mailbox format
My Inbox is 3.5G on disk and I'm happy with my performance.
Mail.app took 8 sec. to search my Inbox for "postfix" but caches mail.
Telnet imap login took 55 sec. for 'search text "postfix"'.
New mail notifications in Mail.app are near instant. I know your old
