Description

Cloned from https://bugzilla.redhat.com/show_bug.cgi?id=1463489

Description of problem:
We did some measurement for number of concurrent registrations with Satellite on default mpm_prefork vs. mpm_event and with mpm_event, we saw significant saving in RSS memory consumed by httpd processes.

Version-Release number of selected component (if applicable):
Satellite 6.2.9

How reproducible:
always

Steps to Reproduce:
1. measure RSS usage of all httpd processes together with default (currently
mpm_prefork) setting during concurrent registration of 140 hosts
2. measure RSS usage of all httpd processes together with mpm_event setting
configured during concurrent registration of 140 hosts

Actual results:
RSS memory usage in first case was about 2 GB, in second case 760 MB.

Additional info:
As discussed, it is important to carefully sanity-test Satellite in regards of functionality and performance.

Re-opening this, as the change that closed this issue was reverted in https://github.com/theforeman/foreman-installer/commit/0ed45f776fdbeb5d5dc814ffeab355da6aefce51

All supported Debian and Ubuntu releases, and EL8 have a sufficiently new Apache httpd, so the only outliner now is EL7.

It was discussed to make it "event" by default, and only use "prefork" for EL7.
