Caliper is Google's open-source framework for writing, running and viewing the results of Java microbenchmarks.

See the Caliper project site, and online result viewer.

The simplest complete Caliper benchmark looks like this:

public class MyBenchmark extends SimpleBenchmark {
  public void timeMyOperation(int reps) {
    for (int i = 0; i < reps; i++) {
      MyClass.myOperation();
    }
  }
}

Very short tutorial examples.

More introductory examples.
