@nisse: Could you please take a look to see whether your CL https://codereview.webrtc.org/1875713002 could have caused this?

Could you give me a little background on what's measured for this graph? 

The only thing done in the cl in question is adding a testcase P2PTestConductor.ForwardVideoOnlyStream, included in webrtc's build target peerconnection_unittests. To me it looks like an unlikely source of the step on the graph.

The graph shows a metric which is produced by the AbsSendTimeSimulcast test in WebRTC/webrtc-win-large-tests/webrtc_perf_tests/ramp-up-media-sent/ but apart from seeing that it has seemed to change I have no idea of what it measures.

Looking at your CL, it indeed looks unlikely that your CL caused the issue.

Reassigning to @holmer.

@holmer: Do you think this could be caused by the CL https://codereview.webrtc.org/1908893003?

Probably. Let's assume it's caused by that. Closing since it's an improvement and somewhat expected.
