Since it sounds like PCP is a no-go with the performance issues, @Ottavia would you mind posting an issue to Issues · theforeman/foreman-documentation · GitHub with details about the problems you are having and perhaps some info about the size of your installation? We can use that issue as a starting point for improving the integration that Foreman advertises. I could then work on getting the issue in front of whoever maintains the PCP integration these days.
