Interesting. Can you elaborate how you measure performance? What's perfoemance? Framer ate, cpu/gpu usage, mem, scroll speed?
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.
