Measuring Java execution time, memory usage and CPU load for a code segment

Question

For a particular segment of Java code, I\'d like to measure:

• Execution time (most likely thread execution time)

Answer 1

Using a Java Profiler is the best option and it will give you all the insight that you need into the code. viz Response Times, Thread CallTraces, Memory Utilisations, etc

I will suggest you JENSOR, an open source Java Profiler, for its ease-of-use and low overheads on CPU. You can download it, instrument the code and will get all the info you need about your code.

You can download it from: http://jensor.sourceforge.net/
