Profiler

Profiler is a simple utility class for method performance test

Profiler.run(threadNum, loopNum, repeatNum, "yourMethod", () -> {
    /* call your method */}).printResult();

// call by method.
Profiler.run(instance, "yourMethod", threadNum, loopNum, repeatNum).printResult();

//call by Runnable and write result to Console with html format
Profiler.run(threadNum, loopNum, repeatNum, () -> {
    /* call your method */}).writeHtmlResult(System.out);

//call by method and write result to Console with html format
Profiler.run(instance, "yourMethod", threadNum, loopNum, repeatNum).writeHtmlResult(System.out);

Here is the result with plain text format:
