Microbenchmarks are used to measure how fast a "micro" fragment of code can perform. If you're wondering how to implement a given functionality or how fast different third-party libraries deal with the same task, then they're the perfect tool for the job. While they're not representative of a realistic environment, they're well suited to perform such small experiments.
Let's show how to run such experiments using one of the most commonly used frameworks to create microbenchmarks in C++: Google Benchmark.
