Red Hat Satellite engineering is moving the tracking of its product development work on Satellite to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "Satellite project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs will be migrated starting at the end of May. If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "Satellite project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/SAT-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

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
All

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
3.

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

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

Comment 1 RHEL Program Management 2015-02-26 20:17:45 UTC 
Since this issue was entered in Red Hat Bugzilla, the release flag has been
set to ? to ensure that it is properly evaluated for this release.
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 
Peter,

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!
Comment 9 Jitendra Yejare 2016-04-27 09:49:57 UTC 
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.
