> Ada is also 2x slower,
  Where'd you get that idea?
When comparing to C, you should remember to turn off all run-time
checking, but even with it all on normal code shouldn't have more than a
10-15% slowdown.  Note that Gnat uses the same code generator as Gnu C, so
one would expect the same semantics to generate the same code and run at
the same speed.  And if you are calling a library of course they would be
the same.  Note also that it's very easy, and safer, in Ada to use
multiple cores, on those occasions when that would help.
