Re: [Evolution] IMAP speed

[Jeffrey Stedfast <fejj ximian com>]

Since no one wants to listen to me, I've spent the past few hours
building Evolution 1.0.8 and deps on my Celeron 400 box at home here (a
multitude of hops away from our IMAP Courier server) and did the
following:

- killev
- rm -rf ~/evolution
- evolution
- create imap account - left on all default options (except I had to
turn on SSL). These options are as follows:

[ ] Automatically check for new mail ...
[X] Check for new messages in all folders
[X] Show only subscribed folders
[ ] Override server-supplied namespace
[ ] Apply filters to new messages in INBOX

- select local Inbox folder (so that the next time we start up it will
not load any IMAP folders, shouldn't be an issue but ah well)
- close evolution
- killev; evolution
- select fejj imap ximian com/INBOX/bugzilla
- immediately start stopwatch
- wait for message-list to load
- stop stopwatch immediately

The results I got were as follows:

Evolution 1.2.0: time = 4:25:48
Evolution 1.0.8: time = 10:09:75

Seems to me that Evolution 1.2.0 is quite a bit faster than Eolution
1.0.8 to me... more than 2 times faster in fact.

Since you come from u.washington.edu, I suspect you probably use
uw.imapd, which may explain your problem - uw.imapd is known to be
extremely inefficient. I would suggest you install a faster imap server
such as Courier imapd or (the even faster?) Cyrus imapd.
