What might be a practical approach to getting more speed would be to use
assembly for the critical bits, and a higher level language for the rest. I
guess you've considered this (?).

It's possible that, in practice, a Fortran compiler might get you a touch
more speed, but this is a guess.

I'd say the difference is not likely to be great between any of those
languages whose compilers are intended to be 'true' native code compilers,
and that the most difference in speed will be due to differences in actual
compilers.

Which Ada compiler do you use (and what is the target machine)? Have you
tried turning off checks (using the Suppress pragma)? I'd be interested to
know if that made any difference!

The saying is "horses for courses". You use a particular language for a
variety of reasons, rather than just speed. If you need raw speed above all,
you probably need to use assembly.

Others might have some data on this.
