[horde] Horde is really really slow on my machine.

You could probably make the machine work for that level of use then.

You're missing my point.  It isn't the external auth/imap service, but
the auth/imap service via horde/imp that I'm talking about.

The test page does no session or authentication; all other pages do.  So
this is why I'm saying the problem may be in the authentication,
session management, etc.

Those pages all involve session management.  All except the login page
do authentications.  So the first thing to check is the speed of session
management.  You should be able to test that on the horde test.php page.
How fast/slow is the session functionality there?

You could also try a php accelerator ;)

Okay.

Yeah, the module type won't make any significant change (very small change
for sure, but not on the scale you are looking for).  For that kind of
change you need a php accelerator.  But I think you have an issue that
can be solved outside of php.

Have you tried it with other browsers/clients?
