Performance Monitoring

To improve the performance of an Ajax application, it is better to monitor the performance for identifying the bottleneck. Depending on the information you'd like to know, there are a few approaches.

• PerformanceMeter: Monitoring the performance from network speed, server-processing time and the client-rendering time.
• EventInterceptor: Monitoring the performance of each event listener.
• Monitor: Monitoring the number of desktops, sessions and other system load.
• There are a lot of performance monitor tools, such as VisualVM and JProfiler. They could provide more insightful view of your application.

For sample implementations, you might take a look at the following articles:

• Performance Monitoring of ZK Applicaiton
• A ZK Performance Monitor
• Real-time Performance Monitoring of Ajax Event Handlers
