This is actually an IMAP problem, not of Emacs Lisp.  (Actually, Emacs Lisp
speed is quite ok on modern machines.)

IMAP provides a "LIST" command which is required to be fast but doesn't give
the status of the folders, and a separate "STATUS" command which is allowed
to be slow and has to be queried individually for each folder.  I would
expect that many IMAP implementations take it to be a license for being as
slow as possible.  I will put it on the stack to consider other possible
ways of doing it.
