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 of problem:

If you go to the activation key page (content -> activation keys), it can take a long time for the page to load. It looks like two calls to candlepin are made for each key, each taking about 300msec.

Ideally, the number of calls to candlepin would not scale linearly with the number of activation keys.

If the activation key page could load each "page" of data in under 5 seconds, that would be much better.

Version-Release number of selected component (if applicable): 6.2.7


Steps to Reproduce:
1. create 20 or 30 activation keys
2. view AK page

Actual results: slow load time. I got 18 seconds locally but I've seen up to 45 seconds.


Expected results: 5 second load time or better

Created redmine issue http://projects.theforeman.org/issues/20584 from this bug

Upstream bug assigned to paji

Moving this bug to POST for triage into Satellite 6 since the upstream issue http://projects.theforeman.org/issues/20584 has been resolved.

Proposed for 6.3.0 since it is fixed upstream

Verified in Satellite 6.3 Snap 33.

The page load times have been reduced significantly. See below averages as well as the attached screenshots.

Load from other pages: 1.8s - 6.5s
Reload: 7s
Switching between paginated AK loads: 0.5 - 1.5s
