How Fast is your Website Really?

September 2022 · View the slides

Monitoring web performance used to be easy - all you had to do was track how long it took for the page to load. However, the extensive use of client-side JavaScript has introduced a raft of new ways modern websites can suffer from poor performance.

New performance problems require new metrics.

With this in mind, Google promotes a set of new metrics known as Core Web Vitals. Core Web Vitals go well beyond directly tracking page load times, instead relying on a set of user-centric metrics that focus on loading, interactivity and visual stability.

In this talk, learn how to capture Core Web Vitals metrics from end users in real time and perform continuous monitoring to quickly react to performance regression as they happen.
