If you set your folder prefix wrong ('folders' parameter in
imp/config/servers.php) it will index the whole account, or the whole
system, rather than the user's folders, and result in slow load times.

Either check what folders it is listing to make sure they are right,
or post your servers.php info and imap software so we can check it.

May not be a problem there, but it is the first thing I would check
given your description.

Including files is apparently a big hit, so Chuck has been reducing the
number of includes recently.  But they should not be such a major hit
as you imply, IMHO.

Any chance it is trying to use this hook?  Displaying quota info
would be a performance hit.

Ideas, but they don't seem so bright ;)
