Benchmarks


When business needs change and your program gets a requirement to perform more efficiently, the first step to take is to find out the areas that are slow in the program. How can you tell where the bottlenecks are? You can tell by measuring individual parts of your program on various expected ranges or on a magnitude of inputs. This is known as benchmarking your code. Benchmarking is usually done at the very last stage of development (but does not have to be) to provide insights on areas where there are performance pitfalls in code.

There are various ways to perform benchmark tests for a program. The trivial way is to use the Unix tool time to measure the execution time of your program after your changes. But that doesn't provide precise micro-level insights. Rust provides us with a built-in micro benchmarking framework. By micro benchmarking, we mean that it can be used to benchmark individual parts of the code in isolation and remains unbiased from external factors. However, it...
