I don't suppose improving your IO is an option? I find turning on dir_hashing in ext3, and mounting my maildirs with noatime, both significantly improve my performance without requiring me to buy new hardware.
I already have both of those options turned on, the problem is that it's running in Xen and I can't get off that right now.
Hmmm, so how many mails in one directory are we talking about?
If Xen is the only thing you can't get out of, have you considered using an alternate filesystem? For example, I hear ReiserFS does very well with Maildir (though I haven't tried it on anything big).
