Optimizing Ajax Applications

As Ajax continues to mature, its use in large, robust applications is becoming more prevalent. However, enterprise-caliber applications require more extensive amounts of code, which leads to the inevitable performance bottlenecks and memory constraints associated with non-trivial application development. Attendees will receive detailed information on how to performance-tune large Ajax applications by using a variety of available tools and techniques. Special attention will be paid to systematic techniques that yield the biggest return in the shortest amount of time, including:

• Mozilla’s Rhino JavaScript engine as a complete performance monitoring tool for Ajax code bases;

• Injecting monitoring code into every function of JavaScript within an application to create a complete performance picture;

• Locating 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
