Bigger perhaps, but not slower. If you hear that from a vendor its just
an excuse. Ada actually gives more information to the compiler than C
and allows it to make more assumptions. There's no reason why an Ada
compiler can't be made to produce *faster* code than a C compiler can.
Of course in practice the difference is in the work put into the
compiler's optimizer, not in language choice.
Of course the user is not blameless in this either. If you don't
routinely put constraint checks in your C code due to speed concerns,
but don't bother to disable the constraint checks the Ada compiler
automaticly gives you, then you have only youself to blame for the
slowness that causes.
