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.

Comment 5 Mike McCune 2018-07-26 18:58:14 UTC
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 pm-sat@redhat.com 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.

Comment 7 Mike McCune 2018-07-26 21:27:15 UTC
*** Satellite 6.3.2 Hotfix Instructions ***

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.
