Here are the results, in seconds, on my machine (2.4GHz x86/Linux) for the suggested input (N=500) from the shootout site. All Haskell versions were compiled with ghc-5.04.2 -O2.
I thought I'd take a stab at timing a few of the examples with different compiler versions to see what difference that would make (ghc-6.2.1 vs. ghc-6.3.20040928). I compared Kevin Everets' version with the two Tomasz Zielonka versions. I ran the test with N=2500 (i.e. 2500 copies of the original file, which is what is apparently used in the shootout) on my AthlonXP 1600 under x86/Linux. 6.2.1 6.3.20040928 ------- ------- Kevin 3.615s 3.156s Kevin (+RTS -G1) 1.666s 1.405s Tomasz (pretty) 0.725s 0.481s Tomasz (fast) 0.403s 0.430s Interesting to see the speed increase going from 6.2.1 to 6.3 for Tomasz' pretty example. Anyone have an explaination for the 2x speed increase for running Kevin's version with '+RTS -G1'?
