@chaopeng: could you check if the improvements in queueing_durations is related to your cl, https://chromium-review.googlesource.com/c/chromium/src/+/1289437 ?

Thank you.

My CL may improve the performance because I ignore all scrolling before the cc side ready.

the queueing duration is down after @chaopeng's cl. Closing the bug.
