Description Peter Vreman 2015-02-26 13:57:19 UTC
Description of problem:
The tasks list is slow. It takes a while to find all tasks:

   Displaying entries 1 - 50 of 10026 in total

With the oldest tasks being 5 months old:

Create user 'API Admin' 	stopped 	success 	2014-09-18 08:43:18 UTC 	
Create user 'Anonymous Admin' 	stopped 	success 	2014-09-18 08:43:17 UTC

Please limit the default view of the task list to a relevant time range of 24h.
Have an UI element quickly change the relevant time range in easy steps:

Last 2h
Last 6h
Last 12h
Last 24h
Last 2d
Last 7d
Last 30d

This limit in timestamp shall also improve the performance of the tasks list

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1. Create 10000+ tasks
2. List Tasks

Actual results:
Slow loading of the data. Many pages available.

Expected results:
Only relevant tasks in the specified time range.

Comment 3 Chris Duryee 2016-03-07 16:40:09 UTC
I tested the speed of the tasks page on Satellite 6.1 and 6.2 (snapshot version):

on 6.1: /foreman_tasks/tasks for 96 tasks, pagination of 20 takes 4692ms
        /foreman_tasks/tasks for 96 tasks, pagination of 10,000 takes 15426ms

on 6.2: /foreman_tasks/tasks for 2035 tasks, pagination of 20 takes 1103ms
        /foreman_tasks/tasks for 2035 tasks, pagination of 10,000 takes 53606ms

I saw similar improvement on a Katello 2.4 installation with >3000 tasks, pagination of 20.

I am investigating more now to see what caused the improvement.

Comment 4 Chris Duryee 2016-03-07 16:59:24 UTC
This appears to be addressed via an index that was added to the DB.

Comment 5 Chris Duryee 2016-03-07 17:07:07 UTC

I believe this bug was addressed by adding an index to the tasks table, which sped things up significantly. I think this makes the dropdown with default of 24h not needed anymore, but if you disagree please reply back to this BZ. Thanks!

Verified !

@ Sat 6.2 Snap 9.2

I tested this with 4493 tasks in 225 pages with 20 entries per page.
Its loading the tasks in expected/reasonable time.

So, moving the bz to verified.
