Yes, it sounds like a complicated, and slow setup, but it's really
easy, and fast too.  I believe the speed comes from Dovecot (or
presumably other well-written IMAP servers, but I haven't tried any
other) is much faster to check for new mail in the maildirs than Gnus.

I have my mail delivered (by TMDA, but that doesn't really matter) to
my maildirs located in ~/Maildir.  There I have

  directory in filesystem (a maildir)  => appears as this on IMAP 
  ~/Maildir                            =>  INBOX
  ~/Maildir/.spam                      =>  spam
  ~/Maildir/.sent                      =>  sent
  etc.

where each maildir is viewed as a folder when Dovecot reads the mail.
I didn't have to configure anything with Dovecot, for it reads
~/Maildir for maildirs by default, and shows any IMAP client what it
finds there.

So, after having renamed my old maildirs to the new .<name> scheme, I
started Dovecot, and configured Gnus with

(setq gnus-secondary-select-methods
      '((nnimap "" (nnimap-address "localhost"))))

on my local machine --- I then got access to my maildirs, but now
going through Dovecot, giving me a significant speedup when starting.

I've also used nnml previously, and it worked fine, and quickly too if
I remember correctly.  The nice new feature of this IMAP-over-maildir
setup is, that I can have other kinds of software accessing the mails
in a proper way and compatible way.
