I am not by any means an expert in compilers/language design. But apparently according to this talk [1] dynamic typing is not the reason JS and other dynamic languages are slow, given the optimizations that effectively "solve" that problem. I would guess that both 1) metaprogramming, and 2) lack of low-level memory management contribute more to the fact that JS is slower than dynamic typing.
