Hi Henrik,

There seems to be a rather large regression in neteq perf stats triggered by a Chrome import (which includes a new Clang version). Several other stats are also affected, but those are generally regressions of less than 10%, while the differences are much larger for NetEq. Do you think this is reasonable or should we look into this?

They all seem to have resolved now with https://chromium.googlesource.com/external/webrtc/+/7f52f084219fdd8003ff0312b81a2a991ad5f572. I cannot see how that CL will improve the performance of our perf tests, but apparently it does. I confirmed this locally on my Linux machine by testing
out/Release/webrtc_perf_tests --gtest_filter=NetEqPerformanceTest.Run
with and without that CL.
