A quick hands-on lesson to learn about Java Microbenchmark Harness (JMH). If you are still wondering about it then this article is for you. Let's explore it with us now.
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.
What Is Microbenchmarking? Learn about microbenchmarking in Java, why it's important, when you should use it, and common microbenchmarking pitfalls to avoid.
What is OpenJDK? OpenJDk or Open Java Development Kit is a free, open-source framework of the Java Platform, Standard Edition (or Java SE).
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.
In this article, we will talk about the most important new feature introduced with Java 10, officially called local variable type inference. An extremely important function in java. You will regret skipping this article.
