  • Mobile Performance

    by Steve Souders

    Before Firebug existed it was hard to know what the browser was doing with your web page. Firebug (and more recent tools like dynaTrace Ajax Edition, Speed Tracer, Web Inspector, and HttpWatch) let us see how HTTP, JavaScript, CSS, the DOM, and rendering take up time as the user waits for the page to load. This visibility into browser performance has generated many web performance best practices as captured in tools like YSlow and Page Speed. The performance evolution that took place on the desktop (tools and research resulting in best practices) is starting in mobile. Right now we’re at step 1: gaining visibility into what’s happening in the mobile browser. Without this visibility, mobile web developers are flying blind. In this session Steve Souders shows how to analyze mobile performance across all the popular devices. He demonstrates analysis tools, services for accessing devices remotely, and quirks he’s discovered that show mobile performance is full of surprises.

    At 1:30pm to 2:15pm, Saturday 16th April
