HaLVM v3: The Vision, The Plan

Galois decided to see if using a higher-level language could help speed up the prototyping process, by porting GHC to run on Xen.

Why is the F# version of this program 6x faster than the Haskell one?

I am finding it difficult to figure out how to write efficient Haskell code.
