Performance is crucial for user engagement, especially on mobile web. Yet users are regularly bogged down by slow page loads, delayed interactivity after page load, high input latency on critical interactions (tap, click, scroll etc), and janky animations or scrolling. These negative experiences turn away users and hurt businesses.

Developers need to measure performance in the real world to get insight into their users’ experiences on the myriad configurations of devices and networks. Unfortunately, many of the techniques used today don’t capture the right metrics or make performance worse.

This talk will cover the new metrics and platform APIs that enable user-centric performance measurement, both in the lab and the real world. We’ll show how developers can track down problems, understand their root causes, and prevent future regressions to ensure users consistently get a great experience.
