Prerequisite knowledge

Attendees should be familiar with web performance history.


At the end of a day spent designing, coding, and performance tuning, what we really care about is the user experience. The problem is measuring this is hard and very often changes from application to application. We use proxies of the user experience that are easier to measure that have been shown to have a correlation, but all we’re really doing is clocking the browser behavior. And what good are detailed web page timings if you are not measuring the right things?

Stephen Ludin offers an overview of the User Timing API, exploring adoption rates, current levels of support, and a path toward universal adoption and usage, and demonstrates how developers can use the User Timing API to measure exactly the critical sections that they want.

This keynote is sponsored by Akamai.
