Engineering HTML5 Applications for Better Performance - a presentation held by Lauri Svan / SC5 at Goto Aarhus International Software Development Conference.
Traditional web services are considered to be slow. The new APIs introduced by HTML5 applications do not automatically perform any better, but provide means for writing them in the same way as native applications.
We suggest to engineer the HTML5 applications the same ways as your native applications. That is, measure them using the same performance metrics, and solving some of the performance bottlenecks in the same ways as you would do for a native app.
