The criterion package

[Tags: bsd3, library]

This library provides a powerful but simple way to measure the performance of Haskell code. 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 documentation and examples in the Criterion.Main module.

Readme for criterion-

Criterion: robust, reliable performance measurement

This package provides the Criterion module, a Haskell library for measuring and analysing the performance of Haskell programs.

To get started, read the documentation for the Criterion.Main module, and take a look at the programs in the examples directory.

Building and installing

To build and install criterion, just run

cabal install criterion

On Mac OS X, the Chart library that criterion uses is not available, so you'll have to build without it.

cabal install criterion -f-chart

This will lose you the ability to generate charts, but you'll still be able to generate CSV files and import them into your favourite spreadsheet, or gnuplot, or whatnot.
