Oh, and because of Dovecot index files it has to do a bit more work than Courier, so with indexes Dovecot POP3 is probably slower for POP3 clients that download+delete all mails, but faster when POP3 clients leave (a lot of) mail lying around on the server. You could get Courier-like unindexed behavior by setting:

mail_location = maildir:~/:INDEX=MEMORY
