[CDBUG-talk] Slow webmail

Further testing came up with some interesting results.
SquirrelMail on host X and point IMAP to localhost = slow
SquirrelMail on host Y and point IMAP to localhost = not slow
SquirrelMail on host Y and point IMAP to host X = not slow
SquirrelMail on host X and point IMAP to host Y = not slow
So it *seems* to be something about using localhost IMAP connections
on the server at work. This is the University of Washington IMAP
server, often called imap-uw or UW or something like that.
I put dovecot on host X (different port that imap-uw), copied
SquirrelMail to another URL on host X, and pointed that copy of
SquirrelMail to dovecot. This was fast. Surprisingly fast. Not sure
if it scales to the level that I need, but its very promising.
This will require a lot of migration work, though. Its not
impossible, but its significant. So I'm wondering why imap-uw would
just suddenly decide to go slower on localhost connections but not
connections from host Y. I might have upgraded it a few work days
before the earliest reports of issues, but there should have been no
configuration changes. Any thoughts?
Thanks in advance,
