Web Performance Working Group

Our Mission

We provide methods to measure and improve aspects of application performance of user agent features and APIs.

The Co-Chairs of the Working Group are Ilya Grigorik and Todd Reifsteck. The W3C Team Contacts for the Web Performance Working Group are Philippe Le Hégaret and Xiaoqian Wu.

We have a primer for Web Performance Timing APIs. That's a good introduction for you.
