I read an interesting article in one of Tartan's (now TI I think)
bulletins on the subject of optimising Ada Vs. C. It explained how Ada
code could be optimised better because of the strict rules on e.g.
function side effects, and how the library system (was it in Ada 83?)
could be used to allow optimisation (e.g. inlining of subroutines etc)
across compilation units in some cases.

Can you quantify that?
