I think I understand what you are saying. It does keep registered flows.
Anyway, here is what I tested it on. Then I also did a version of hub
that registered flow instead. Now when running iperf I can see the
throughput difference between the hub and switch implementations. Hope
its ok.

On monitoring, I found your fork and am going to take a look at the
webservices bit. 

Thank you.
