Measuring Site Speed with Navigation Timing

What makes great user experience? Users’ thirst for speed seems increasingly unquenchable. Even as they (barely) tolerate the sluggish performance of mobile devices, they demand more and more of their PCs. Make them wait one blink of an eye too long, and they are gone, taking the revenue they would generate with them.

In 2010, The World Wide Web Consortium chartered a Web Performance Working Group to give developers client-side tools, in the browsers, to gain greater visibility into the timing of each aspect of page loading and help them see how they can make their pages faster. The first product of the working group is the Navigation Timing API, which Keynote is already leveraging to provide more granular site performance reporting and to provide operations managers and developers a common language to address site improvements.

If you want the complete picture on the user experience, read an interview with Microsoft IE Program Manager Jatinder Mann a Microsoft IE Program Manager Jatinder Mann lives and breathes performance, both on the Internet Explorer team and on the W3C Web Performance Working Group, and is an expert on the Navigation Timing API. Benchmark recently caught up with him to get an overview of the Navigation Timing API and other initiatives and what they offer the Web community.
