Yeah, have a look on the shootout: http://shootout.alioth.debian.org/gp4/benchmark.php?test=recursive&lang=all Has an ackerman. More detailed comparisions, across the 19 benchmarks on the shootout, with notes on which of the 19 GHC Haskell is significantly slower (>4x) at: Haskell verus Python http://shootout.alioth.debian.org/gp4/benchmark.php?test=all&lang=ghc&lang2=python Loses on: regex-dna Haskell verus Ruby http://shootout.alioth.debian.org/gp4/benchmark.php?test=all&lang=ghc&lang2=ruby Loses on: regex-dna Haskell verus Perl http://shootout.alioth.debian.org/gp4/benchmark.php?test=all&lang=ghc&lang2=perl Loses on: regex-dna Haskell verus Lisp http://shootout.alioth.debian.org/gp4/benchmark.php?test=all&lang=ghc&lang2=sbcl Loses on: mandelbrot (Double math) spectral-norm (Double math) Haskell verus Clean http://shootout.alioth.debian.org/gp4/benchmark.php?test=all&lang=ghc&lang2=clean Loses on: k-nucleotide ( HashTable benchmark) mandelbrot spectral-norm Haskell verus SML http://shootout.alioth.debian.org/gp4/benchmark.php?test=all&lang=ghc&lang2=mlton Loses on: k-nucleotide mandelbrot spectral-norm Haskell versus OCaml http://shootout.alioth.debian.org/gp4/benchmark.php?test=all&lang=ghc&lang2=ocaml Loses on: k-nucleotide mandelbrot regex-dna spectral-norm Haskell versus C Loses on: k-nucleotide mandelbrot regex-dna spectral-norm Fixing these last few programs: k-nucleotide: Needs a better hashtable library implementation. For example a Data.HashByteString based on a Trie of ByteString) regex-dna: Should use the regex-tre library instead of regex-posix (algorithm issue only) mandelbort/spectral-norm: Double math is slow. I don't know why. And note that strings aren't a bottleneck anymore! http://shootout.alioth.debian.org/gp4/benchmark.php?test=sumcol&lang=all -- Don seth:

GHC has profiling support.

(By the way, many mail servers these days discard mail with no subject.)

I've seen a number of papers comparing the speed of Haskell code to code of other functional languages; there is a periodic "shoot out" with ocaml.

Some probably have comparisons with imperative languages, and, even if they do not, the methodology should help you.

Hello everyone,

I did at my master thesis a compiler that generates Haskell code. Now I need to measure the execution time of my generated code and I've been searched and I don't know if I'm looking with the wrong keywords but I could not find anything. I just need to measure the time of simple functions, like Ackermann and Fibonacci. Does anyone know how to measure the execution time of a Haskell program or function?

Thank you, Tays
