Errata Install to Content Host takes too long and doesn't scale well
Cloned from https://bugzilla.redhat.com/show_bug.cgi?id=1288152
Description of problem:
When applying (installing) errata on a Content Host from the server, it takes a very long time.
For example, installing ~556 errata on a single content host was observed to take ~44 minutes. Most of that time (~36 minutes) was during the 'initiating the install' phase of the task (i.e. executing the pulp consumer content install). While this may not sound too bad a first glance, it won't scale well as the behavior is linear. As a result, if there were 100 content hosts, that same action could take ~3 days.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. install Satellite 6.1.4
2. import a manifest
3. enable and sync the RHEL 6Server RPM repo
4. create a content view containing the RHEL 6Server RPM repo and publish it
5. register a RHEL 6.5 client to the above content view
6. initiate an errata install from the UI
(Hosts -> Content Hosts -> select the host -> Errata -> scroll through
all of the errata, select them and 'Apply Selected')
Observe that the errata are installed on the content host; however, it takes a very long time to initiate and execute the task.
We need to investigate why it is taking so long to initiate the errata install and look for ways to optimize it to improve performance.
Attaching a foreman debug from the server where the above scenario was executed.
