JChav is a way to see the change in performance of your Web application over time by running a benchmark test for each build you produce. It is an Ant task that, when used in conjunction with the JMeter ant task, produces historic views of the performance of your application. Charts are produced for individaul pages of the application along with summary data. If integrated with cruise-control or similar build tools, you will get an idea if the changes you are making to your Web application are improving or degrading performance.
