1245793 - investigate responsiveness metric for osx

Status: RESOLVED INACTIVE

(Testing :: Talos, defect, P3)

we are turning on responsiveness metric (chrome only, not content) in bug 710296.  This posts ~55 for non-e10s and <10 for e10s.  For osx, sometimes we get values like this, but normally for both e10s and non-e10s, we get something in the 70K-80K range.

This puts doubt into either the responsiveness collection, or the osx 10.10.5 configuration we are using in automation.

:jimm, can you look into this or find someone to look at it as you have expressed an interest in responsiveness?

For reference, the main implementation in Gecko is here:

and the Mac-specific bits are here:

To be clear, this isn't e10s specific, but we're interested in having this data for measuring e10s
