mflodman@: I've done some digging on the causes of these perf regressions and I wonder if they could have been caused by the CL
https://codereview.webrtc.org/2165743003 ?

If not, do you have any other suggestion about what could have caused the regressions?

I can't see that this CL should have any effect at all for this test, since the number of audio streams is 0 and this is an audio only change.

Stefan,
I'm assigning to you to decide the impact of this and next step for a possible investigation.

Hmm, putting back on me for now to investigate.

Per,
Not sure I'm reading this correctly or not, but this is what I see:

One of the two graphs points at something between 13625-13649, the CL above is 13527 and not in that range. 

The other is in the 13712-13715 range, so shouldn't be there either.

holmer@: Could the webrtc-android-tests-nexus9 tests be related to the CL https://codereview.webrtc.org/2201093006? 

The webrtc-android-tests-nexus9 seems to possibly be related to that, but the 
webrtc-android-tests-nexus72 are likely caused by something else.

Please reassign back to me after having a look at the webrtc-android-tests-nexus9 tests, and I'll then have another look into the webrtc-android-tests-nexus72 tests.

It's probably related to that and therefore I think it's ok to close. I expected metrics like those to be affected.

It's not impossible that the nexus7 metrics also are related to that CL.

Great! Thanks!
I'll then close this.
