2.3%-100% regression in webrtc_perf_tests at 14815:14821

Project Member Reported by phoglund@chromium.org, Nov 3 2016 
Looks like the level controller tests have regressed to a new level. The graphs are a bit noisy, and maybe these tests are bit too sensitive? Commit positions 15-21 or so are implied, and this gives us this blamelist:

Similar to https://bugs.chromium.org/p/chromium/issues/detail?id=659767.

... And they're just on a single bot, which lowers confidence in these results. If they're true, this regression looks to be mac only.

Comment 4 by kjellander@chromium.org, Nov 3 2016 

I filed several perf bugs last week for level controller metrics, so I think this may be a continuation of those... I'm quite sure my GN refactoring is innocent.

Comment 5 by peah@chromium.org, Nov 10 2016

Status: WontFix (was: Assigned)
It does not make sense that these regressions occur from this CL.
I think it is an issue with the test and I have filed a webrtc bug for this (https://bugs.chromium.org/p/webrtc/issues/detail?id=6685)


I will close this issue, as the absolute size of the regressions is small.
