Details

There is code in WebRender to record and classify slow frames. The classification is rather basic, it shows information such as:

  • whether the slow frame was dominated by frame building or rendering (and which sub-phase of the two)
  • whether the slow frame happened during scrolling
  • whether the slow frame happened just after layout changes

It would be useful to get this information in telemetry.
