Abstract

Haskell makes it possible to write elegant, high-level code that rivals the performance of low-level, imperative languages. In this tutorial, I will introduce the tools Haskell provides for reasoning about the performance of your code and techniques that you can use to make your code faster. I will cover important topics in Haskell performance optimization, including:

By the end of the tutorial you should have an understanding of how to accurately measure the performance of your Haskell program, determine which parts of the program needs improvement, and finally, improve the performance of the program.

Audience

Experienced programmers familiar with functional programming. Familiarity with Haskell will be useful, but not required.

Software prerequisites

Haskell Platform 2010.1.0.0 (or later) and the Criterion benchmarking library. The latter can be installed by running

cabal install -f-Chart criterion

after installing the Haskell Platform.

The Haskell Platform can be downloaded for Mac, Windows, and Linux from:
