When searching for something online, people often open multiple results in browser tabs and switch to the one that loads first. It’s a race for the user’s attention, but usually there’s only one medal.

Just as in sport, the web is fiercely competitive and people expect more from it each year. Last year’s winning performance is this year’s new baseline. As a result developers must answer complex questions to stay in the game: How do users perceive the performance of my site? What do they expect and am I meeting their expectations? What new metrics should I be collecting to answer these questions?

Not complicated enough? Put mobile devices in the game. Do mobile users have different expectations than desktop users? How does radio link lifetime affect performance? How do I work with the lack of NavTiming support in mobile browsers?

In this talk, Buddy and Philip will answer most of these questions, and cover some of the insights gained from studying real user performance data over the last few years. We’ll also cover tools that you can use, both free and commercial, to arm you with the information you need to win Gold.
