#1808 Organizations load is slow and CPU intensive in v.2.6.1

[Switchfoot]

I have two iTop installations on the same server with the same setup and data but in two different iTop versions 2.6.0-4294 and 2.6.1-4463. Both installs have about 500 organizations in the database, each of them has one of two Parent organzations defined. iTop v. 2.6.0 works fine. Version 2.6.1 however has a problem with performance when organizations are being loaded. For example in User Preferences > Favorite Organizations > All
or in Search for Person Objects > Organization > (Magnifying glass) > All

Seems like a duplicate of [#1747], do you confirm ?

[Switchfoot]

It might be related to [#1747], but I am not sure it is a duplicate, because we do not experience the issues with any other objects besides organizations, and the problem occurs in firefox and IE.

[Pierre Goiffon]

The 1747 bug is triggered when :

• opening a selectable list of items
• relatively lots of items in the list (can occurrs with just some dozens)

All browsers are concerned, and impact in IE is certainly the worst (old JS engine).

Can you try to apply the fix ? See https://github.com/Combodo/iTop/commit/3c4fe338b61b5de67e9edf070e5b02a79f4c0eba

Hi Pierre,

thank you for the fix. It works, but the performance is still somewhat 4 times worse than it used to be in v. 2.6.0
Here are the load times I measured:

With 511 organizations in the DB and the user Preference setting of "Default length for lists" set to 600, the full load auf the "Preferences..." lasts:

• -- ------------------ |Firefox 52.9 ------- | IE 11 ------------ | Chrome 78
  v2.6.1 without fix | never (> 5min) ---| never (> 5min)-- | 1min, 45sec
  v2.6.1 with fix -----| 3 sec -------------- | 8 sec -------------| 3sec
  v2.6.0 -------------- |<1 sec -------------- | 2 sec -------------| <1 sec

Thanks for this feedback !
Can you try to see where is this time consumed using your browser dev tools ? To identify if it is server side or client side ? In Firefox, that would be in the network tab.

[Switchfoot]

When performing multiple tests using firefox dev tools I get similar reload times for the same preference page in v2.6.0 (0.94-4.30 sec) and fixed v2.6.1 (2,15-4,93sec). So I think my previous timed realoads were just an imprecise coincidence and the ticket can be closed as a duplicate of the already fixed #1747.
Thank you very much for your help!
