How to measure the performance of virtual scrolling in a production environment？

[lwxsanshui]

In fact, I can view the local performance through the FPS tool in devtools. But how do I know the actual performance of users in the production environment

There are multiple ways. So if you have an error checking program such as Sentry, you can enable live performance monitoring for each request, track request time and user misery.

So you can track the requests. Other than that you can seed a bunch of data to mimic a production client and use that as baseline when testing locally.

Good luck
