Red Hat Satellite engineering is moving the tracking of its product development work on Satellite to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "Satellite project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs will be migrated starting at the end of May. If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "Satellite project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/SAT-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Description of problem:
Bug 1793875 that we previously open and fixed didn't actually fix the slow rendering issue. It just allow the page to load asynchronously but the slow host listing issue is still persist in the job invocation page.

 
Version-Release number of selected component (if applicable):
foreman_remote_execution-4.2.3

Steps to Reproduce:
1. In the setting page, set the default page size to 250 or higher
2. Run a remote execution jobs against thousand of hosts
3. Login as a user with only viewer permission
4. Go to the job invocation page

Actual results:
- Host list takes extremely long time to load
- Duplicate many duplicate requests are send to the Satellite every 1 second. This is because the WithInterval/auto refresh doesn't wait for previous request to complete. (Will open a separate bugzilla for this)

Expected results:
- Host list shouldn't take long to load.

Verified on Satellite 6.10 snap 13, no significant slowdown experienced in the aforementioned scenario.
