We're already there [1] for vectorized code (Haskell vs. Hand written C). Note how they compare naive haskell solutions with their vector library vs. heavily optimized C code and using finely tuned libraries. And they are competitive, actually beating the finely tuned library in non-toy examples while still using naive haskell.
