A quick hands-on lesson to learn about Java Microbenchmark Harness (JMH). The article helps you get started and configure JMH project.

Introduction

In my previous article, we established that microbenchmarking is hard with jvm. It is not enough to surround the code in a loop with System.out.println() and gather the time measurements. While benchmarking, a developer should consider warm-up cycles, JIT compilations, JVM optimizations, avoiding usual pitfalls, and even more.

Thankfully, OpenJDK has a great tool Java Microbenchmark Harness (JMH) that can help us generated benchmarking stats. In this article, we will discuss how JMH can help us avoid the pitfalls that we have discussed earlier.

Java Performance Optimization

Getting Java apps to run is one thing. But getting them to run fast is another. Performance is a tricky beast in any object-oriented environment, but the complexity of the JVM adds a whole new level of performance-tweaking trickiness — and opportunity. This Refcard covers garbage collection monitoring and tuning, memory leaks, object caching, concurrency, and more.
