But that's not a very good thing to compare. What does it tell you? That C is faster than Perl for a very specific case of tight loops and integer arithmetic that is rendered totally moot by the existence of a trivial O(1) algorithm.
What it doesn't tell you is whether Perl, Inline::C, PDL, or this VB-inspired DLL is a good choice for any real-world problem. It does not implement an interesting algorithm, so you can't compare which provides the most readable implementation; and it does not benchmark an interesting calculation, so you can't really compare performance either.
