Description Chris Duryee 2016-04-26 21:02:33 UTC

Description of problem:

The 'sync status' page gets slower as the number of products and repos grows. It appears that there are two areas that cause it to be slow.

First, https://github.com/Katello/katello/blob/master/app/controllers/katello/sync_management_controller.rb#L29 can be very slow. With 10 custom products and 7 enabled RH products, it takes about 7 seconds for that line to complete.

Secondly, a call to candlepin to fetch subscriptions is made for each RH product enabled. Each of these takes 300-400msec.

To repro, import a manifest and enable a few repos on some RH products. Sync all products to get some sync data, then view page.

NOTE: this is a performance optimization bug for the sync status page. Ideally, there will be no change in functionality.
