[Bug 234525] [NEW] kmail imap unduely slow

[Vu Ngoc San]

Public bug reported:

On a slow connection, kmail+imap is almost impossible to use due to its slowness.
My connection is particularly slow in the outgoing direction (about 10kb/sec).

What I don't understand is that attachments are supposed to be
downloaded on demand, but each time I check for mail, it takes for ever
when some messages have big attachments. Opening the "task list" I see

1. downloading message data. This is reasonably fast
2. sending message data. This is very slow. It seems to me that all attachments of all new messages are sent back to the server !!

The second step always occur, even if I don't click on messages with attachments.
Due to this, it is really IMPOSSIBLE for me to use kmail.

I have to use thunderbird, which has no problem at all. Everything is
fast and responsive with thunderbird (with the same IMAP server).
Attachments are downloaded only when I click on the message, and they
are not sent back to the server ! Dealing with messages with attachments
is about 20x faster with thunderbird...

I'm very sad of this because I like kontact very much.

(forgot to say I have a brand new kubuntu hardy 8.04)
