NewsWhen Haskell Is Not faster than C PinstaffTerrence Dorsey21-Jan-13 12:10 
I’ve earned a good part of my life’s income to date taking other people’s C code, cleaning it up, making it work and then making it work better. In one sense the original program that this article is about is perfect, it takes the prescribed input, processes it and produces the desired output using the test set provided. That’s really all you can ask for in any program, under normal circumstances. Provided of course that the program produces its results in an acceptable time. What acceptable is is up to the user of such a program, in this particular case the writer of that article (linked at the end) used acceptable to mean ‘slower than Haskell’ and as a long time observer of the language wars this irks me.
You need to write the code correctly before you can benchmark it.
