I am looking for a performance profiling tool that can tell me the performance bottlenecks in my Java application and can give me a detailed overview of the most expensive method calls.

I have the following requirements:

  1. I have a Java Enterprise Application, so the profiler should be able to measure the performance of the Java server application when some request arrives.
  2. I am using JSF, Spring, and Spring Webflow. If some request arrives and as a result flow x is executed, the profiler should be able to list the performance of all methods called during the execution of flow x.
  3. The profiler should be as lightweight as possible.
  4. I am working on Linux with IntelliJ IDE and it would be great if the profiler has a IntelliJ integration for source code navigation
  5. If possible, the profiler should be open source or at least there should be a free trial version.

Currently I am facing the problem that my server needs a lot of time for responding on certain requests and I want to know if there is any single method that is very slow or if the number of method calls is the problem.

    The microbenchmarks in JDK9 would be useful for this. – NonlinearFruit Feb 10 '17 at 14:36
  • @NonlinearFruit microbenchmarks seem to be worth trying. Currently I am working with a trial version of JProfiler. This profiler offers detailed statistics of method execution and it is easy to control. – siebenschlaefer Feb 22 '17 at 8:40
