163041 - Opening already downloaded IMAP message in separate window is slow

Status: RESOLVED WORKSFORME

(MailNews Core :: Networking: IMAP, defect)

Description

[Fredrik Aminoff]

When opening a large mail (~800kb, no attachement) over an IMAP-connection
Mozilla seems to download the whole message again. I have already downloaded and
see it in the preview-pane so Mozilla should be able to open it fast. Mozilla
seems to hang with 100% CPU usage and "Loading Document" and the new blank
mail-window. After a very long time the mail is shown and the CPU-usage drops.

Using:
Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.1) Gecko/20020814

i got sort of the same problem - without the cpu usage - the message just
downloads itself again when opening in new window, eventhough i've just viewed
it in preview-pane.

I get the same behavior on this build as well.

Nikolay - pretty sure this is a dupe

Wayne, I don't recall any dupes right now, but had personal problems with early 2.0.0.0(4) and probably with latest 2.0.0.12 2 weeks ago.

I was about to dupe this against bug 345832 when noticing "no attachments" in the original description, thus not sure if this is the same mechanism.

Also, introduction of an IMAP disk cache (bug 439731) or using off-line storage by default (bug 385502) may resolve this issue as well.

Fredik do you still encounter the issue with recent builds of thunderbird ? (http://www.mozillamessaging.com/en-US/thunderbird/early_releases/ to find such a beast)

I've gotten a fairly much faster computer since 2002, so the problem is not as easy to duplicate anymore. :)

Running "version 2.0.0.19 (20081209)" I did however still see this to some extent. However not always and not in the same problematic way.Some of my mails did load slow when opening up them in a seperate window with a "loading message" status.

To summarize. If you would like to close this bug based on the above, it would be OK with me.

storing messages offline by default helps here a lot. Marking wfm.
