Yes, fast execution.  I have been using C.  In my applications there is
a population of "chromosomes" which are arrays of floats, about 2 to 5 k
in length.  Then there are subroutines which operate on a chromosome
using pointers.  For example, the "crossover" routine uses two pointers
to swap portions of two chromosomes.  My software sometimes runs for
hours, perform many millions of operations like these.  Clearly, speed
of execution is of dramatic importance.

A related problem is that it seems to be a big deal to call C routines
from Python.  I have not actually tried it, because when I read about
how its done I was not able to understand it.
