1042704 - Thunderbird 31.0 takes too much resources

Status: RESOLVED WORKSFORME

(Thunderbird :: Untriaged, defect)

Description

[Dan Pernokis]

User Agent: Mozilla/5.0 (Windows NT 6.1; rv:31.0) Gecko/20100101 Firefox/31.0 (Beta/Release)
Build ID: 20140716183446

Steps to reproduce:

Installed TB31 (upgrade from 24.6.0).  Ran TB as usual.
Run TB - move the mouse in circles - problem shows.
Do a GET MESSAGES - problem worsens permanently.
Quit TB - problem goes away.


Actual results:

Mouse becomes sluggish, especially noticeable after doing GET MESSAGES.
Windows Task Manager shows 5% to 7%, Norton NIS Performance shows 6% -- even when TB is idle.  

(Mouse is USB)


Expected results:

TB should have no visible effect on operation of the mouse (or any other device).
Windows Task Manager never showed a percentage above zero except in rare instances, likely fetching something, and TB rarely showed in Norton NIS Performance window.

Start *Windows'* safe mode with networking enabled
- win7 http://windows.microsoft.com/en-US/windows7/Start-your-computer-in-safe-mode
Still In Windows safe mode, start thunderbird in safe mode
- http://support.mozillamessaging.com/en-US/kb/safe-mode

Does problem go away?

This is embarrassing...

I was going to restart WIN/SAFE as you suggest, but as usual I did a Norton update prior to shutdown.  It failed, twice, and the log shows it had been doing so since 3 am here.  I rebooted (normally) to resolve the Norton issue first, which it did, again a usual occurrence.

So then I launched TB -- and no mouse hesitation.  Ran GET MSGS (ALL) several times, nothing noticeable at all on the mouse.  Then I launched MS WORD and Google Chrome (sorry, my alternate screen browser for testing) which had been open concurrently before too.  Again, no mouse delays.

Wayne, you're a genius!  I should have thought to reboot before reporting the bugs.  Turns out it may have been a Norton issue.  (Our laptop has a BT mouse, and has no hesitation issues.)  Sorry about this.

no problem - I also need a reminder from time to time.

You might contact norton to tell them about their problem.
