If we knew that, we would have already told you, no?

And so what processes is top showing using the CPU?  And as I've asked
before, is the speed problem at login and every 3-4 minutes there after,
running quickly between those times? Or is it always slow?  At least now
you've said it isn't under high user load, so that helps.

No Turba?

Yes, something is.  What?

Why starting there?

Yes, it is.  It also has yet to see its first official 1.0 version

Or using the "officially unsupported" configuration files...

I seriously doubt it, but who knows.  At first you said it had to be
Horde/IMP because you didn't change anything else.  Then you said the
login problem was because you updated UW-IMAP.  So who knows what
else it could be.

Personally I'd guess your slow login is turba and the problem is
your turba/config/sources.php, but that is only based on the fact
that a lot of other people who have slow logins reported to the list
have this problem.  Since you won't answer any questions about your
problems or provide sufficient details, I can't really make a very
educated guess as to your problems.
