JMH, the microbenchmark harness has an example that highlights this: https://github.com/openjdk/jmh/blob/master/jmh-samples/src/main/java/org/openjdk/jmh/sample

  And since benchmarking is hard is also has a helper to actually "waste" time. [1] The implementation [2] might give an idea that it is not always trivial to do nothing but still appear busy. Btw I found most of the jmh samples interesting. IMO a quite effective mix of example and documentation. (and I'm not sure there is even much other official documentation) [1] https://github.com/openjdk/jmh/blob/master/jmh-samples/src/main/java/org/openjdk/jmh/samples/JMHSample_21_ConsumeCPU.java https://github.com/openjdk/jmh/blob/master/jmh-samples/src/m...
