Performance issues

[lbayle]

Hi,
Firefox complains about a page slowing down the browser.
It takes a long time to display the "Assignment board" (+200 issues to display)

Very promissing tool, we already love it !

+1 for this issue, we have 280 tickets under the filter of My View page and it took forever to load.
Please fix this issue

Further investigation is I only filtered out the status and the other filtered set to default. May some issue with the selecting datas queries?

Taskodrome/Taskodrome/pages/main.php

Line 34 in 58a15c5

$t_per_page = -1;

is causing for me to that over 32 000 records per page is configured. Main document loads in 2.1 minutes and there are errors in js console, missing buttons on page and I see no tickets.

When I change $t_per_page to null it causes configuration of 50 records per page, main document loads in 7s but it still takes way longer to show some tickets. Records per page probably shouldn't be unlimited?

Related to js performance I found that when commenting out this while:

Taskodrome/Taskodrome/files/scripts/utils.js

Line 106 in 23af0e0

while (resWidth > maxWidth || resHeight > maxHeight) {

rendering time drops by ~1min.

In case you're interested I started working on performance improvements: https://github.com/imatic/Taskodrome/commits/imatic_mantis2 for now js renders page with 50 records about 1minute faster (many long strings which this plugin was shortening quite a while).

Hello, @nenadalm !
Thank you for help! I'll check out your commits.

[nenadalm]

Do I understand it correctly that this plugin just renders all issues in mantis in selected project? So that if I have over 32000 issues, they will all be rendered at once (status doesn't matter) and there is no way to configure it?

[AuthenticEshkinKot]

Yes, this plugin gets all available issues of current project and tries to show them. Admin can hide some users or statuses with their issues using plugin configuration.

[nenadalm]

Plugin configuration won't affect number of rows from database though:

Taskodrome/Taskodrome/pages/main.php

Line 38 in 58a15c5

$rows = filter_get_bug_rows( $f_page_number, $t_per_page, $t_page_count, $t_bug_count, null, null, null, true );

right? So no matter what I configure, plugin will always fetch all 32 000 issues?

[AuthenticEshkinKot]

Yep, that's right

[nenadalm]

Ok, thanks. It turned out that this plugin is not something we would like to use. Feel free to merge in the performance improvements in case of tasks with long texts. I won't look more into this.

Could you make a pull request with your improvements, please? It's your work, so it would be more fair if your account would be attached to it.

[nenadalm]

I don't think I can. I am getting redirections when trying to create PR: https://github.com/mantisbt-plugins/Taskodrome/compare/mantisbt-plugins:mantisbt_2.0.0...imatic:imatic_mantis2?expand=1 back to the create PR page. I don't really mind which account is attached to the changes :)

[AuthenticEshkinKot]

OK :)
