883159 - Usage memory of Firefox grows quickly and slows Firefox when using multiple tabs for IBM Requirements Manager

Status: RESOLVED INCOMPLETE

(Firefox :: Untriaged, defect)

Description

[sandrine.soudant]

User Agent: Mozilla/5.0 (Windows NT 5.1; rv:21.0) Gecko/20100101 Firefox/21.0 (Beta/Release)
Build ID: 20130511120803

Steps to reproduce:


When I use IBM Requirements Manager with Firefox v21, memory usage grows quickly as I open new tabs and slows Firefox.

How to reproduce :
1. Here are manual operation with timestamp and memory usage trace (in Kb)
08:42   Open Firefox v21 on WinXP SP3 4Go RAM with 3 tabs (webmail Google and 2 calendars)   235 608   
08:45   Open a 4th tab to IBM Rational Requirements Manager (v4.0.2)  server  278 720   
08:48   Click on "Display modules"   307 672  
  08:48   Open 2 new tabs on the woking module (tabA and tabB)   400 907   
08:51   Nothing special, I use RM to find artefact and make tracability with tabA and tabB   510 010   
08:53   on tabA, display a shared view with the "Todo stuff"   479 508   
08:53   on tabA, find an artefact to perform
08:53   on tabB, find the previous artefact, I like have some context informations to do tracability, and set answers artefarcts  
09:27   open 2 new tabs to have 2 others module for answers  500 212   
09:28   8 tabs are opened, firefox is slow  675 904  
09:50   open and close a few tabs (2 ou 3, no more) to retrieve answering artefact and return with only 8 artefacts 991 268
11:20  open a new tab to fill this issue 1 247 689, firefox is very slow

Twos weeks ago, I used the Firefox cache with default configuration for cache properties. Memory usage grows slowly but Firefox was slowly quicker.
Last week, to improve performance, I use a proxy on a distant server to cache data and I don't use Firefox cache. Now memory usage grows quickly but Firefox is faster.
How to improve correctly firefox to have a fluent use with a correct memory usage ?


Actual results:

During a working day, Firefox comes slowly and his memory usage reaches 1,5 Gb and it's too slow to be use normally.
As far as I know, the workaround is to restart Firefox.



Expected results:

Fluent use with IBM Requirements Manager with less than 10 tabs.

Do you know if it's possible to use online IBM Requirements Manager? It would help to debug and test.

In addition, could you create a new profile with Firefox (see the FAQ: https://support.mozilla.org/en-US/kb/profile-manager-create-and-remove-firefox-profiles) then reproduce your steps to increase memory use with IBM Requirements Manager.
Then type about:memory?verbose in the URL bar and save the entire memory log, then attach it (as .txt) to the bug.

Hi,

No chance to use IBM Requirements Manager online, you can use a trial version.

Without possibility to test (online e.g.), I don't know how devs will be able to fix a possible bug...

Anyway, you could provide on your side the memory log I requested in comment #2.

With a Firefox with no additional plugin.

Sorry, that's not the right format.

If your version of Firefox is new enough to have a "Measure and save..." button in about:memory (or something similar), please use that and attache the resulting .json.gz file.

Otherwise, please copy and paste the contents of about:memory?verbose into a text file and attach that.  You can compress this file if it's big.

Thanks!

Actually, I can read it ok.

Here's the top of the data:

That last line (event-targets) is XHRs, which is interesting.

But generally I don't see anything too alarming here.  I suspect that IBM Requirements Manager is just a really heavyweight app, and when you open multiple tabs it'll just unavoidably take up a significant amount of memory.  Have you done any measurements in other browsers to see how they compare?
