This is interesting... what did you use for these tests? Existing
checked in clients or some custom benchmarking tool?
Were the senders and receivers paired? I.e. did each sender send to one
specific receiver? Or did each sender broadcast to all receivers? How
did you measure the throughput?
One of the key experiments I would like to see is a measurement of how
overall throughput can scale out when adding extra routers. So e.g. for
a broadcast pattern, with publishers publishing at some fixed rate, see
how many publishers and receivers can be supported at that rate by one
router, then add in a second router and see how many more publishers and
receivers the combined network can then handle. (A similar test could be
done for unicast).
