789826 - regression: large text mails (>500k) slow display and lock-up in seamonkey 2.12

Status: RESOLVED WORKSFORME

(SeaMonkey :: MailNews: Message Display, defect)

Description

[Jan Hoogenraad]

User Agent: Mozilla/5.0 (X11; Linux i686; rv:15.0) Gecko/20120826 Firefox/15.0 SeaMonkey/2.12
Build ID: 20120826214918

Steps to reproduce:

I use seamonkey to display output from cron-jobs.
Output is often a new Mb.
Using seamonkey < 2.12, these text files were loading while one could scroll, ans click on other messages.


Actual results:

Starting seamonkey 2.12, my computer (4-core 3 Ghz) lock for several minutes (!) while loading a text E-mail. During this time nor the browser, nor E-mail is responsive. 
This way, one cannot go to a smaller (and thus faster) message to stop the application.


Expected results:

Mail should display at least the first part of such a large mail quickly.
Fast behaviour as in seamonkey < 2.12 should be restored.

SeaMonkey 2.12.1 fixes some (but not all) performance problems with mail handling. Do you still see this problem with 2.12.1?

I'm back at (for me) the stable release 2.11
I tried to use the updater. 
However: the updater does not work. It says "Update failed" "The integrity of the update could not be verified".
I'll hang on 2.11 till the updater is fixed.

You can update manually, using the steps below, which assume that your system is 32-bit Linux (for other OSes there is a similar but slightly different procedure) and that your SeaMonkey distribution is installed in /usr/local/seamonkey (for instance, "type seamonkey" at the shell prompt points to /usr/local/bin/seamonkey and "ls -l /usr/local/bin/seamonkey" shows a softlink pointing to ../seamonkey/seamonkey). If SeaMonkey is installed elsewhere, change the following instructions accordingly.

1. From http://www.seamonkey-project.org/ download SeaMonkey 2.12.1 and save the archive (seamonkey-2.12.1.tar.bz2) anywhere convenient.
2. If SeaMonkey is running, close it, and wait until it is completely closed. This can take a few minutes after all its windows have closed. You can watch KDE System Guard or Gnome System Monitor and look for a big drop in both CPU and memory use. Then type "ps -lC seamonkey" at the shell prompt and if the answer consists only of column headers but doesn't mention any "seamonkey" process, it has indeed closed. Otherwise, wait some more.
3. Remove your current installation, e.g. by typing "rm -Rvf /usr/local/seamonkey" without the quotes at the shell prompt. This will not remove your extensions (if any), your preferences, your profiles, nor indeed any of your customizations; it removes only the program itself.
4. Unpack the file downloaded at step 1, typically by using "tar -jxvC /usr/local -f seamonkey-2.12.1.tar.bz2", again without the quotes at the shell prompt.

That's all. Whatever softlink pointed from somewhere in the $PATH to the old version should now happily point to the new version, so that any "seamonkey" desktop icon you had will now run the new version, and typing "seamonkey" (or, maybe better, "seamonkey > seamonkey.log") without the quotes at a shell prompt will also start it.

BTW: I filed Bug 790167 for the broken update.

Used the new update. Speed of text mail display is OK again. Thanks
