Benchmarking with BenchmarkDotNet

BenchmarkDotNet is the industry-standard .NET benchmarking library, trusted by the runtime team and thousands of developers to measure code performance with statistical rigor. It automatically handles JIT warmup, GC collection, thread-pool tuning, and statistical analysis—so you get actionable, reproducible results instead of misleading timings. This series teaches you how to design, run, and integrate benchmarks from your first test through production CI pipelines, covering setup, parameterization, memory diagnostics, baseline comparison, and common pitfalls that trip up newcomers.

Whether you're optimizing a critical algorithm, evaluating a third-party library, or monitoring performance regressions in your build pipeline, this series equips you with the tools and patterns used by real .NET teams. You'll learn why naive timing loops fail, how to interpret confidence intervals, and how to build a sustainable performance-testing culture in your codebase.
