YMMV; the only way to know is to try it. :) In any case, Maildir will still be hideously slow to read, compared to mbox (which can get pretty slow when you have 100MB mboxes like I do, and I'm sure lots of other people do.) for your ordinary pop3 user tho; they won't see a difference. (and we'll definitely see an improvement on the server side, since file locking isn't a bottleneck anymore.) anyone have experience with SQL-database-backed mailservers? how do those perform, compared to mbox/Maildir?
