I wonder why they found Haskell to be so slow, I thought it was compiled.
The first reason for the performance of programs is how much care the
programmer has to write a fast program, secondly how good the chosen
algorithms are, and only then at a third place there are language
implementations.
So the short answer to your question is that most of the Haskell
programs of Rosettacode are not written for performance. The corollary
is that performance comparison is silly/bogus.
Often the faster programs of Rosettacode are in... guess a language?
Yes, in D. Because I have written also performance conscious D entries
(sometimes I have added various D solutions, at various levels of
performance, succinctness, safety & correctness).
I wonder why D appeared only scarcely in this paper. -- Andrei
