There are quite a few methods to measure performance

We start of with the FPS monitoring tool which measure the frame rate, memory consumption and GPU sange

We switch to devtools->Performance analysis to measure function call times, layout thrashes and shifts, RAF bottleneck, memory consumption and CPU time.

We also use React devtools to measure re-rendering.

Scrolling is wrapped in Request animation frame loop, hence its being controlled by the browsers frame rate.
