Description Duncan Wilcox 2002-02-21 09:03:19 UTC 
Please fill in this template when reporting a bug, unless you know what you
are doing.
Description of Problem:
When Evolution is checking mail on a large IMAP account -- I have over 50
folders with mail delivered directly to the folders via procmail, it is
extremely hard to do anything else, particularly it is extremely slow to
switch folders or even switch between messages within a folder.

I have checked my IMAP server (courier imapd 1.3.5_1 running on FreeBSD
4.4, configured to allow 4 connections per client), and it appears to be
only ever using one server to serve all Evolution requests, so it appears
that Evolution is  using a single connection.

It would be nice to be able to optionally enable an additional connection
to the server for interactive tasks, to keep the UI responsive, so "Storing
folder ...", "Scanning folder in ...", etc. would use the backgound
connection, while "Refreshing foler ...", "Retrieving message ...", etc.
would use the interactive connection.

Steps to reproduce the problem:
1. Connect to large IMAP account
2. Send and receive mail
3. Switch folder or message

Actual Results:
Folder/message switching is very slow

Expected Results:
Folder/message switching is an interactive operation and should be fast
enough to make the UI usable.

How often does this happen? 
Always.

one of the problems with this is that not all imap servers actually
allow multiple connections to the same account (uw.imapd for example,
which is also the most popular because it is installed by default with
most linux systemsand even other unix systems).

anyways, this will require a complete rewrite of IMAP no matter how
you figure it so it will be quite a while before we get around to it
(we do have other reasons to want to rewrite imap though...)

marking this as "probabledup" because I want to mark this as a
duplicate of the "IMAP rewrite" bug.
