APZ Regressions

Talos numbers listed on this page are pulled from the Perfherder e10s dashboard. These results include the affects of enabling APZ on mozilla central. The component of individual regressions and improvements associated with APZ is listed below and is based on a Perfherder comparison between a try run with APZ disabled and mozilla-central. Test that showed no change are not listed.
