I haven't seen this behaviour on the box right now. Which makes me think the slowness happens, when something else is happening as well. I've notices however one thing yesterday: when switching tabs in the hosts list page while the job is running, every tab switch causes additional recurring polling to be sent to the server: jumping though several tabs can lead to 10s requests per-second: this might influence both the memory cunsumption in general (the more requests like this, the more passenger processes will be used) as well as response times
and therefore I suspect this could lead to slow response time times of job invocation page. I will provide a patch today to test if this might help with the problem

Moving this bug to POST for triage into Satellite 6 since the upstream issue https://projects.theforeman.org/issues/20776 has been resolved.

Comment 11 Roman Plevka 2018-09-13 11:48:25 UTC

VERIFIED
on sat6.4.0-21

the page of a job invocation for 5000 hosts (with some of them still active) got loaded in about 3 seconds.
there are no more calls being made to insights for the preview template.
