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 Mike McCune 2018-07-25 22:31:08 UTC 
1) Take large Satellite installation with 20,000 content hosts
2) Navigate to Content Host -> Pick a host with applicable Errata
3) Click Packages -> Applicable Packages
4) On large installations this page will never return (query takes 4h+ to complete).

During execution of said query, Postgres will consume 20-40GB of disk swapping out the query results, consuming way more resources than it should and slowing overall operations of the Satellite.

You can test this even on a Satellite with ~1000-2000 Hosts with applicable errata. The page will take 30-40 seconds to load before this patch.

With this update it will render quickly in under a second.
Comment 6 Satellite Program 2018-07-26 20:08:54 UTC 
Moving this bug to POST for triage into Satellite 6 since the upstream issue http://projects.theforeman.org/issues/24389 has been resolved.

Verified in Satellite 6.3.3 Snap 2.

I setup over 4k content hosts, each with 376 applicable packages.

Following the steps outlined in the initial report, I saw that that load times, of the applicable packages page, only took a couple of seconds. This is significantly lower than the 30s load times expected with only 1000 content hosts.
