Ruby Strikes Back, then Fails

Conclusion
Ruby is faster the OCaml. Wrong! OCaml is a lot faster than Ruby. But thanks to hard work by some prominent Rubyists you can have a Ruby setup that performs decently enough to make you proud.
It is amazing to see that Ruby people (or I should say RoR people instead ?) still can keep them proud from this benchmark.
They should proud how easily they can build things in RoR rather than the speed. Or... is it not easy in reality?
