    Description

      In load testing, we discovered a significant increase in the database CPU load, and a corresponding increase in the site.upd events logged. The root cause has been identified as the placement.save() method invocation in the PortletIFrame.popupXFrame() method.

      The immediate workaround is to disable xframe caching with the following sakai.property:
      iframe.xframe.cachetime=0

      Longer term, we need to determine why the property setting is not being read from the cache as expected.
