Scrolling Event

[AbigailMonday]

We would like to have the ability to monitor our scrolling performance.

Our use-case involves rendering a big amount of dynamic data. We use windowing to only render the relevant data each time, so scrolling causes newly-presented data to be rendered.
Scrolling events will be very helpful to monitor performance in this case.

Thanks for the feedback! We do intend to add measurements to look at scrolling performance in a future version of the API. In particular, I think it would be useful to expose cases in which the scrolling takes a long time to render or is blocked on javascript execution.

By the way I imagine this is related to actual scroll-gesture-to-pixel performance and not the performance of the scroll event itself, right? In that case we plan to solve performance measuring of that via the Frame Timing API. You can see an explainer at https://docs.google.com/document/d/1t3A56iTN01ReEELJ18_jLYrvc13L3hDTXWK46AafKwE/edit, I'm closing this for now but let me know if this does not address your issue!
