Foreman Issue Tracker 20508 0 'Normal' 'Closed' 'Extremely slow /api/v2/hosts, 200hosts/page takes about 40s to display' 2019-11-11 14:06:38 UTC

Description Justin Sherrill 2017-09-14 17:29:28 UTC 
I noticed this when l try to pull up the content hosts view or when I was using the foreman plugin for ansible.

In short, the @/api/v2/hosts@ call takes a very long time. With jsherril's help I've extracted some debug logs (attached). It looks like most of the SQL time is spent in lookups to rpms and errata with some more in reports.

suggesting for 6.3, as it should help performance on the hosts api and pages.
