I once compiled a OCR program for the Amiga and one of the things I did
was trying to enable optimization for higher order processors. On my
060-equipped Amiga this gave a speed increase in the range of 25-30
percent. This is certainly worth taking into account in my opinion.
However, this is of course pure computations with no real interfacing
with the system -- as soon as you start using the system libraries the
optimization might be of little importance.
If the optimizer is shitty in other ways, I don't know. I have at least
never experienced any problems with it. It is indeed slow, but SAS/C has
never been known for being a fast compiler.
