* how to speed up connection to a imap server @ 2008-10-20 9:51 Uwe Brauer 2008-10-20 10:44 ` Tassilo Horn 0 siblings, 1 reply; 7+ messages in thread From: Uwe Brauer @ 2008-10-20 9:51 UTC (permalink / raw) To: ding Hello It seems that the connection to my imap server gets slower and slower (I have agentized the server). I have the following setting (setq gnus-secondary-select-methods '( (nnimap "ucimap.ucm.es" (nnimap-stream network)))) Is there any way of speeding up the connection to that server, by setting additional parameters depending on the character of this imap server? Like setting the nnimap-server-port explicitly to 143 so something like this. thanks Uwe Brauer ^ permalink raw reply [flat|nested] 7+ messages in thread

I think you've already done that implicitly by setting nnimap-stream to network and thus forbidding encrypted connections. Is that really what you want? The overhead of encrytion (if there's any) won't make a difference compared to the normal network latency. The only thing that will speed up things quite a lot is to install a local imap server and let gnus connect to it. Syncing between ucimap.ucm.es and the local server can be done with offlineimap [1], for example.

Well yes, the 993 port is dead slow :'( > The only thing that will speed up things quite a lot is to install a > local imap server and let gnus connect to it.

I use dovecot. It's not too hard to configure and doesn't have a big memory footprint. And I use offlineimap to sync my two imap accounts with the local dovecot server. Several others on the list use the same setup, AFAICT. Bye, Tassilo ^ permalink raw reply [flat|nested] 7+ messages in thread

Well the devecot server is also a debian/ubuntu pkg and so I installed it. Is it too much to ask you for your configuration files (without psswd and other information). For devecot, offlineimap and gnus. That would be a great help. I presume you run offlineimap periodically via cron or something like this. Maybe it would be a good idea to include such a configuration example also in the gnus manual. regards Uwe PS when using F runs `gnus-article-followup-with-original' it seems that gnus only answers to the list but no cc to your from address, I just wonder what is the reason for this. ^ permalink raw reply [flat|nested] 7+ messages in thread
