Mastering High Performance with Kotlin

Benchmarking

It's difficult to compare the performance of algorithms simply by looking at their descriptions or pseudocode. It's better to run actual implementations on a real system. This method of measurement is called benchmarking. There are three categories of benchmark:

• Microbenchmarks: These are metrics showing the performance of certain functions. They assume that a small piece of business logic is contained in a single function, and we simply measure how fast this function runs.
• Macrobenchmarks: These are the opposite of microbenchmarks; they test the entire application.
• Mesobenchmarks: These are something in-between, measuring features or workflows.

Large applications more or less contain certain critical pieces of code. The JVM ...
