FORTRAN Optimization/Performance

Has anyone out there done any performance benchmarks on Digital's
FORTRAN compiler on either NT or Digital UNIX?? From the tests I've
run so far, it seems that the 'f2c' route I'm using on Linux is not
capable of generating code that can get the pipeline architecture
of the Alpha processor running without stalling. I'm hoping that
the Digital compiler is capable of getting the chip into pipeline
mode and am hoping someone can share their experiences.
If interested, I have a series of simple floating point tests that
look at basic operations to determine what a system's weak points
are and what it's strong points are. My main interest is with single
precision floating point but the tests also look at double precision
and integer arithmetic too.
Any info/pointers are appreciated.
