In PolyMix, you specify peak request rate. That rate, naturally, will
correspond to some peak throughput (proportional to mean response
size).  Looking at last cache-off reports, 2500/sec load approximately
corresponds to 135 req/sec.

You can modify PolyMix-4 response sizes and/or request type
composition to get the desired throughput for a given load. This
modification will require some experimentation to get the resulting
throughput right, since the traffic model is not simple. Your results
will not be, strictly speaking, PolyMix-4 results then. If your
customer needs PolyMix-4 results, they should not ask for both load
and throughput levels.
