Microbenchmarking overview

Microbenchmarking is used to test the performance of a system. This differs from macrobenchmarking which runs tests on different platforms for efficiency comparison and subsequent analysis. With microbenchmarking, we typically target a specific slice of code on one system such as a method or loop. The primary purpose of microbenchmarking is to identify optimization opportunities in our code.

There are multiple approaches to benchmarking and we will focus on using the JMH tool. So, why benchmark at all? Developers do not always concern themselves with performance issues unless performance is a stated requirement. This can lead to post-deployment surprises that could have been avoided if microbenchmarking was conducted ...
