In app/models/katello/glue/pulp/repos.rb#last_sync, Katello first searches for repo sync tasks and then audits if no sync tasks show up when attempting to find a sync time for repositories within the product.

However, if the product has no synced synced repositories, it seems that the audits search is very slow. It may be because the lack of audit record is causing the entire audit table to be scanned.

Should the last sync time be stored on the product itself?
