Has anyone been benchmarking SLES vs RHEL v3 beta?  One of my codes
is twice as fast on a dual 1.4 Ghz opterons with RHEL v3 beta as compared
to a dual 1.8 Ghz opteron running SLES.  

The application is an earthquake simulation using MPI, I used the newest
MPICH with the same compiled features, and am running 2 processes in
both cases.
