The main problem is that it's difficult to do any "real world" tests with IMAP, especially when users are using many different kinds of IMAP clients. So I'm very interested in hearing some numbers (and disk IO graphs for a few weeks would be great) before your migration and after your migration, but the numbers for your tests might not mean all that much.
I was considering using the imaptest tool to simulate IMAP activity. I would keep the same machine configuration, only varying the mailbox format while running imaptest against each setup for a few hours/days.
I'm now converting the original Maildir format to both dbox formats and I'll give it a try. I'll share some graphs afterwards.
