Performance-Tune Your AJAX Application

[microbee]

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. This session provides 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, this session will look at a variety of performance bottlenecks that can occur within an application. Special attention will be paid to systematic techniques that yield the biggest return in the shortest amount of time, including: *Using Mozilla's Rhino JavaScript engine as a complete performance-monitoring tool capable of monitoring complete 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. *Start time optimization using Dojo, Gzip, Compression.
