Could you try running it with a "no" crafty.rc file.  That way it would be more
comparable.  It looks like your machine "sees' 1.116 million NPS per second on
the standard crafty bench with your particular crafty.rc file.

For comparision against dis-similiar machines - all machines should run the same
"bench" with the same settings - typically achived by using "no" settings or
without any configuration or crafty.rc file.  One check for single CPU machines
, total nodes searched should equal across all platforms.  Your total nodes
searched is different from my bench - either we have different versions of
crafty or we are using settings are different.  I know we are using different
settings - I'm not sure about different versions until I see your total nodes
searched with "no" crafty.rc file.
