Hello all!

Are Event.Latency.ScrollBegin.Wheel.TimeToScrollUpdateSwapBegin2 on desktop and Event.Latency.ScrollBegin.Touch.TimeToScrollUpdateSwapBegin2 on android key metrics for input-team?

Could you please give full list of key metrics for scrolling?

Do you have any key metrics for whole browser? I know Memory.Renderer.Large2 and Memory.Total2 are key metrics.
