You mean the Ada *compilers* you looked at seem to be slightly slower than the
Fortran *compilers* you've looked at. The language itself is not slower, only
the implementations you may have looked at. As I said in another post, there's
no reason why someone can't put the effort into making an optimizing Ada
compiler that's better than any optimizing Fortran compiler. The problem is that
some (not all) Fortran compiler writers care about optimization more than your
typical Ada compiler writer does. If you compare one of these uber-optimizing
Fortran compilers to a random sample of Ada compilers, of course you're going to
see a big difference. It would be odd if you didn't.
