Subject: expiry taking "forever" in both cpu time and real time when the IMAP UID is high
Date: Thu, 02 Dec 2010 13:17:21 +0100 [thread overview]
Message-ID: <871v609xny.fsf_-_@nemi.mork.no> (raw)
In-Reply-To: <1291291383-18946-1-git-send-email-bjorn@mork.no>
And then after having implemented the IMAP internal copy speedup, I
noticed that the "fetch all articles which are about to be expired one
by one" code isn't the worst part of the expiration process...
After copying the articles, Gnus does "something" which evidently
depends on the UID value. When expiring from my work INBOX, which now
is using UIDs in the 280000s although it usually only has a few hundred
messages, emacs will eat 100% of one CPU core for a loooong time
(several minutes).
So I did a simple experiment with my home courier-imap server: I changed
the UID value of one article to a high value (>100000) by editing the
courierimapuiddb file, and then tried to expire this article. This made
Gnus go into the CPU burning mode. There is obviously something going
on which doesn't handle high UIDs very well. This happens right _after_
the actual article copying, while waiting for the *Group* buffer to
reappear.
Any hints? Anyone else seen this?
Bjørn
