Just an idea, but have you evaluated performance of mdbox (new dovecot 
format) on your storage devices?  It appears to be a gentle hybrid of 
mbox and maildir, with many mails packed into a single file (which might 
increase your performance due to fewer stat calls), but there is more 
than one file per folder, so some of the mbox limitations are avoided?

I haven't personally tried it, but I think you can see the theoretical 
appeal?

Good luck
