After upgrading to 1.4.8 (from 1.4.7), I noticed a sharp increase in XenForo's application response times according to NewRelic. As you can see in these graphs, most pages were generated on the server in approximately 30ms; after the update, that has changed to 50ms - an increase of nearly 66%. Note that I performed the upgrade at approximately 12:00AM on June 27th. There were no other changes or upgrades performed at this time. This is a dedicated CentOS server running @eva2000's Centminmod. PHP-FPM 5.4.42, MariaDB 5.5.44. Any ideas on what might have caused this?
