When I worked at Lincoln Labs, the performance of the UNIX (4.1) f77 was
compared against the VMS FORTRAN, in (I believe) an application for digital
signal processing.  VMS FORTRAN came out (as I recall) as twice as fast as
the f77 compiler (resulting code, not speed of compilation).

A 4.1BSD C version of the same program was 10% faster than the VMS FORTRAN.

The result is left to the reader as an exercise. :-)
