We have a slight regression in dromaeo dom:
http://graphs.mozilla.org/graph.html#tests=[[72,131,33]]&sel=none&displayrange=7&datatype=running

I did some retriggers to help verify the exact changeset:
https://tbpl.mozilla.org/?tree=Mozilla-Inbound&fromchange=db25dbf0e8d0&tochange=e09be54f43d6&jobname=Ubuntu%20HW%2012.04%20mozilla-inbound%20talos%20dromaeojs

While this is a slight regression the patches from bug 957086 show a clear drop in the numbers (lower is worse) as prior to this the retriggers show a 4800-4900 range and for this changeset we dip into the 4700 range for most of the values.

I really don't see why bug 957086 would have affected Dromaeo scores unless it's a PGO artifact.  But do we actually do PGO on this platform?
the test is regression on non pgo, we do pgo and it appears we have regressed there as well:
http://graphs.mozilla.org/graph.html#tests=[[72,131,33],[72,63,33]]&sel=1401107828173,1401712628173&displayrange=7&datatype=running
on aurora we seem to have an overall win (higher is better):
http://graphs.mozilla.org/graph.html#tests=[[72,63,33],[72,131,33],[72,52,33]]&sel=1397236726302,1405012726302&displayrange=90&datatype=running

so I will unblock this from firefox 32.
