Using JRat

You can use the Java Runtime Analysis Toolkit (JRat), an open-source performance profiler for the Java platform, to identify potential performance bottlenecks, especially if your deployment uses custom Java classes. JRat monitors your application’s execution and persists the application’s performance measurements.

For example, if you have a custom workflow for provisioning, you can use JRat to see which classes are being invoked and how much time is required to run your workflow compared to the default Waveset provisioning workflow.
