This is heresy but I disagree.

Different languages make fundamentally different choices resulting
in very different kinds and amounts of knowledge that is provided to the 
compiler.

Assuming an approximately constant level of knowledge and resources
between compiler groups this can make a huge difference in the speed
of executable code.
