Steps to Reproduce

1. Hop to any Orlando Instance. 2. Set up adding records to a related list on agent workspace. Refer below documentation. https://docs.servicenow.com/bundle/orlando-servicenow-platform/page/administer/workspace/task/set-up-adding-records-to-related-lists.html 3. create more than 1 Million records in the cmdb_ci table. 4. Go to the Agent workspace and open any incident. 5. Go to Affected CI related list and click on Add button.

Expected: The records should load as soon as we click on the add button. Actual: A popup shows 0 items selected initially but leaving it aside for some time shows up the actual records.

Workaround This is expected behavior and by design in all currently supported releases.
