The numbers from Intel were good, but they were on a single-cpu Itanium-2
machine.

Eugene's were also from a single-cpu Itanium-2 if I recall correctly.

One issue might be the compiler.  Eugene obviously has the latest since he is in
the
compiler group at MS.  Intel may be using a beta MS compiler or their own, I
don't
know.
