Thanks for taking a look at this. IMAP and backend DB are on their own
dedicated servers. Horde is running on six app servers which use an imap
proxy to connect to the IMAP server. Only the IMAP server was overloaded,
the others showed no significant change in performance after the upgrade.

I'm wondering if it's either (a) the virtual inbox making heavier use of
IMAP or (b) changes to the way Ingo accesses IMAP when doing its filtering
work. But these are just guesses really. Let me know if there's any other
information I can provide that might give a clue. Thanks again.
