    You haven't mentioned whether you verified that the output from the no
    command on the production box and clone show any discrepancies. When we
    cloned an S80 (that was SP-attached) to an H70 (stand-alone), our throughput
    declined dramatically as well. We discovered that several values established
    by the system for the H70 were dramatically different than those in place
    for the S80 (which may have been enhanced by being a pseudo-SP node). Just a
    thought ....
