   If I am interpreting your message right, you are trying to compare
three systems: one with just an '040 running, and two with both an '030
and an '040 running.  If this is what you are asking, I have an easy
answer: they will all produce exactly identical results.

   The reason is that neither AmigaDOS nor UNIX (the two operating
systems you can run on an A3000) support multiprocessing.  For this
reason, you can only have one processor running the benchmark, and the
'040 is the one that runs the benchmark.  In all three systems, the
'040 in the CPU slot will be running at 25Mhz, with the '030s 
sitting idly by waiting for a multiprocessor operating system to
be written.

      I hope this answers your question.
