Running courier for a five user setup on an old P90 I cannot really comment on multi thousend user setups, but I must second this based on years of experince with different mail setups. On any serious IMAP server, you need fast I/O subsystems. If you use NFS, take some time to tune it properly.
Theoretically the FS choosen should make a difference as well, try it out. On Linux, reiser was designed for the type of access that imap on maildir has, lot's of relatively small files. Try it out to see if it makes a difference. Note that tools for reiserfs do not completely integrate with some distros, expect some trouble (The fsck takes different flags than the normal flags, on RH/Fedora this means boottime fscks go all haywire, YMMV but I advice not to check your rieser partitions on boot).
