See here: https://www.gnu.org/software/emacs/emacs-paper.html#SEC18

Even with byte compilation, I'd have to see benchmarks to believe that
the speed difference between dynamic and lexical binding in Emacs is
significant, especially with a small amount of coding attention, such as
using LET outside rather than inside a tight loop if you can.

RMS is a pretty sharp Lisper and while anyone can be wrong about things,
I tend to want a pretty good reason to think I'm not the one who's
wrong.  In the previous section of that paper (SEC17) though, he does
say,

   It is not necessary for dynamic scope to be the only scope rule
   provided, just useful for it to be available.

That roughly fits the situation in CL, Scheme, and modern-day Emacs
Lisp.
