straightforward implementation dolist is going to be faster, since it will give rise to a simple loop, whereas mapcar will have to be called as a subroutine, and then it will call its functional argument at each step of the iteration. However a smart compiler can expand mapcar into inline code, so that the difference in speed is negligable.
