Interpreters can give good results on the Savage benchmark since most
of the time is spent on the tan(), exp(), etc.  To judge the suitability
of a language system for number crunching you need to check integer
and simple-FP-ops performance too!

From what I've gathered by now, if you want to crunch numbers you should get
a FP chip.  On the ST, you should use Absoft Fortran.  (Alcyon and MWC are
not that far behind, though, and Alcyon (like Fortran) allows single-precision
when you need the speed and don't need that much accuracy.  Does MWC?)

I suggest we gather here some benchmarks about the speed of typical +-*/
FP operations (a complete statement of the form: "a=b+c;" - that's the
only way to benchmark!!!).
