Correct on your last comment.  We are using the C version of Stream and
the Portland Group C Compiler, although GCC does nearly as well.  There
is, to me at least, reason to believe there is a lot of headroom for
performance gains as compilers are made more aware of Athlon
optimizations and the same for Intel systems.
