Description

What type of manifest did you have? 1 subscription with a quantity of 1000+, or lots of little? That may be where it turns a little strange. The manifest I initially loaded only had a couple of subscriptions (3 at most). Now, there are 999 (or maybe more). While I think there is still some validity to this, I may need to run these tests again with a known good manifest. If the subscriptions in the manifest are using virt_limit there would be one pool created for each system bind (which is for 4 guests on that specific host). This could explain the explosion in pools. They should not however be affecting performance in recent versions of candlepin. (should be fixed since around candlepin-0.7.9-1) The version of candlepin in this case is candlepin-0.7.8.1-1.el6cf.noarch. I can re-run the tests with a later candlepin to see how it fares. Upstream has been updated to candlepin-0.7.19. This contains the fix for this issue. When candlepin-0.7.19 is moved to a CFSE branch, this should be moved to ON_QA. Moving all POST bugs to ON_QA since we have delivered a puddle with the bugs. VERIFIED. Og Maciel registered and subscribed 1000 clients with no errors or no delay.
