# Scroll Framerate

Scroll performance is critical to user experience. Janky scrolling is one of the most noticeable performance issues - users immediately feel stuttering and frame drops when swiping through lists, feeds, or grids.

Make sure to read [the overview guide for performance analysis](index.md).

**Example Prompts**

> Scroll through the list of items on <screen-x\> and measure the framerate. Highlight and investigate any transitions that are performance outliers.
>
> Scroll back through history in this screen as fast and as far as possible. Generate a timeseries of swipe # against available performance data
