As AJAX matures as a technology, its use in large applications has increased significantly. But large applications require more extensive amounts of code, which leads to the inevitable performance bottlenecks and memory constraints associated with non-trivial application development. In this session, Bob will provide detailed information on how to performance-tune large AJAX applications using a variety of available tools and techniques.

Drawing on the experience of having developed large AJAX frameworks, Bob will look at a variety of performance bottlenecks that can occur within an application, paying special attention to systematic techniques that yield the biggest return in the shortest amount of time.

Specific topics covered:
• Use Mozilla's Rhino JavaScript engine as a complete performance-monitoring tool capable of monitoring complete AJAX code bases;
• Inject monitoring code into every function of JavaScript within an application to create a complete performance picture;
• Locate performance issues through drilldowns of function call counts, total time spent, average time per call, and call stacks and start time optimization using Dojo, Gzip, Compression.

Speaker Bio: Bob Buffone, chief architect at Nexaweb Technologies, is responsible for platform and tool technology at Nexaweb, a provider of the Nexaweb Platform enabling enterprise class rich Internet applications (RIAs). He is also a committer on the Apache XAP Project, which provides an extensible framework for declaratively creating AJAX applications.

2008  Will Be The Decision Year for RIAs
AJAXWorld Conference & Expo 2008 will provide delegates with the optimum balance between RIAs, Rich Web Technologies and AJAX, while underlining business needs, technology potential, and enhanced user experience.

This year at AJAXWorld the relentless focus is not only on where RIAs are now but also where Rich Web Technologies are headed, where Enterprise Web 2.0 and Social Applications are taking the software development industry and the end user, and how Rich Web Technologies are transforming our businesses and our lives.

Delegates will learn how RIAs are making money and gaining market-share for some of the leading businesses in the world.

The real-world questions that will be answered by this year's 140+ sessions are those that currently preoccupy working developers, architects, IT managers and business line managers. The 2008 tracks include:

• Enterprise RIAs and AJAX
• Rich-Web Case Studies and Mash-Ups
• Enterprise Web 2.0 & Social Applications
• Event-Driven Web
• iPhone Developer Summit
• Diamond Track

AJAXWorld is sponsored by the world’s leading RIA technology providers including.

Conference faculty includes the world’s top RIA experts.
