Go programmers have the good fortune of excellent testing and benchmarking tooling built into the standard library - in the testing package. However, benchmarking is hard. This isn't Go specific; it's just one of those things experienced developers learn over time.

This post lists some common benchmarking pitfalls Go programmers run into. It assumes basic familiarity with writing Go benchmarks; consult the testing package documentation if needed. While these pitfalls are presented in Go, they exist in any programming language or environment, so the lessons learned here are widely applicable.
