Loading a message in message pane is very slow. It occurs both on POP and IMAP account. Build date and platform tested: 1999-11-04-09-M11, windows commercial build. Platform: Win 95, 133 Mhz, 64 MB RAM. Additional info: 1. Time taken to load a 10 kb Msg on 11/04 build is ~15 seconds. 2. Time taken to load the same msg on 10/22 build is ~4.5 seconds.

Since this is both POP and IMAP, let's start with rhp.

suresh, do you want to attache a copy of the msg to this bug report? rhp - does it help if we paste in any output from the DOS console?

Output isn't really that helpful...but the message would be good. David, what was the barber poll performance issues that you were working on before. I have a feeling this may be a part of what we are seeing. - rhp
David...forgot to add you on the last update. - rhp
The attachment isn't the message contents I need. What I need is the actual contents of that file from your mail folder. Do this: - send this message to a 4.x client - select message - save it as "BUG.EML" - attach this file with a content type of "message/rfc822" - rhp

*** Bug 17535 has been marked as a duplicate of this bug. ***
This problem may be related to my bug: Bug #17062 for slow message display times on Linux. I'm pretty sure that problem is related to all the event queue changes which did go in between the dates Suresh noticed the problem: 10/22-11/04. I suspect this is the same problem. Although it's reported on windows and not linux.
Summary: [perf] Loading a msg (10 kb) in message pane is very slow. → [DOGFOOD] [perf] Loading a msg (10 kb) in message pane is very slow.
I'm going to nominate for DOGFOOD since this has to do with performance and is something many people do (read msgs).

I did some investigation with mscott on this issue. From what we saw, it doesn't look like libmime OR Necko are the culprits here. Even without getting exact timing, it was obvious that the OnStartRequest and OnStopRequest are processed fairly rapidly, and then there is a significant delay after we write our data to layout. mscott believes this is due to a forced reflow bug with the throbber running and we can see what almost looks like a multiple repaint of the message. mscott is investigating this issue under a different bug so I am marking this as a duplicate of that problem. - rhp *** This bug has been marked as a duplicate of 17062 ***
