High Performance in Rich Web Apps: Five Practical Strategies and How to Implement Them
Yahoo's Eric Miraglia to Present at SYS-CON's AJAXWorld RIA Conference & Expo, Oct. 20-22, in San Jose, CA

Those of us in the business of writing rich Internet applications have seen the focus swing from how to add richness to how to manage richness and the resources it demands in the browser. Steve Souders's recent volume from O'Reilly, High Performance Web Sites, and the canonical performance rules Steve pioneered with the Exceptional Performance Team at Yahoo in recent years have helped bring data-driven order to the lore that surrounds browser performance.

Once you've followed the rules, though, there remain a number of steps you can take to improve the way your application feels for the end user:

  1. You can be lazy, enriching your application on-demand in response to the user's actions;
  2. You can be smart, using predictive triggers to load specific pieces of data or functionality;
  3. You can be courteous, yielding control of the browser's JavaScript thread while performing long, complicated operations;
  4. You can be environmentally astute, reducing the number of JavaScript and DOM objects by reusing them where ever possible;
  5. You can be cost-conscious, always analyzing the real price you're paying on the performance side and recirculating that information into the design process.

In this session, we'll look at all five of these practical strategies and how to enact them on your project. You'll walk away with ideas for how you can make your project more responsive immediately — including code snippets, where appropriate.
