Hackage Matrix CI

This library provides a powerful but simple way to measure software performance. It provides both a framework for executing and analysing benchmarks and a set of driver functions that makes it easy to build and run benchmarks, and to analyse their results.

The fastest way to get started is to read the online tutorial, followed by the documentation and examples in the Criterion.Main module.

For examples of the kinds of reports that criterion generates, see the home page.
