HPjmeter

HPjmeter is a tool to assist you in tuning your Java programs for best performance. Usually, program tuning requires three consecutive steps:

  1. Run the application with profiling enabled to collect the profiling data.

  2. Display the metrics, and analyze the performance of your application. Find out which parts of the program are responsible for heavy resources use. Remember the 10-90 rule: in most cases 10% of the program code is responsible for 90% of the resources used.

  3. Re-engineer your program and try to improve its performance.
To achieve best performance, you should iterate this process many times.
