Gcc to IMAP is slow

Gcc to IMAP is slow

[Vegard Vesterheim]

In order to preserve threads as much as possible, I Gcc my own messages
both into the folder I am in, and to the Sent-folder (via
gnus-outgoing-message-group)). But this is now much slower than before
the IMAP rewrite. My emacs can get unresponsive for many seconds after I
have sent a message. The imap log shows that gnus is doing a IMAP SEARCH
for a Message-Id, which I guess can be slow on large folders:

09:45:15 920 SELECT "INBOX"
09:45:15 921 UID FETCH 1:* FLAGS
09:45:16 922 APPEND "INBOX" {786}
09:45:16 923 UID SEARCH HEADER Message-Id "<1ssjzuk96c.fsf@voll.uninett.no>"
09:45:22 924 SELECT "Sent"
09:45:22 925 SELECT "Sent"
09:45:22 926 UID FETCH 1:* FLAGS
09:45:22 927 APPEND "Sent" {786}
09:45:22 928 UID SEARCH HEADER Message-Id "<1ssjzuk96c.fsf@voll.uninett.no>"

Any hints on how to fix this?

FWIW I do the same thing with BCC and letting it hit the same procmail
filtering that handles incoming email.

I don't do that, though.  Why two copies?

Yes, I could do that, but it seems kinda silly to send the message on
this round-trip, when I can stash it directly in the correct folder
directly.

Primary laziness, it makes searching for my own sent messages much
easier.

This seems unnecessary and probably very slow.  Fixed now.

However, this is necessary to mark messages as read if you have
`gnus-gcc-mark-as-read'.  If not, it's probably not very useful, but it
isn't slow on the servers I've tried it on...
