Introduction
Optimisation of code is an endless struggle. It is often even hard to produce meaningful metrics using jvm
as it is an adaptive virtual machine. The article is
- a brief introduction to microbenchmarking,
- why microbenchmark,
- when to consider it, and finally,
- pitfalls to avoid
What Is a Microbenchmark
A microbenchmark is an attempt to measure the performance of a small unit of code. The tests are usually in the sub-millisecond range. The tests can help determine how the code is going to behave when released into production. These tests are guide to a better implementation.
