Benchmarking is the process of measuring and baselining the performance of your code. It helps identify bottlenecks in comparing the performance of different algorithms or approaches that target the same set of problems and choosing the one that has optimal time and memory consumption. There are many ways to code the same thing in .NET, so how do you know which one is more performant? There can be big differences that not only affect performance but memory too. This article describes how I use BenchmarkDotNet to benchmark my code.
