The switch should give more bandwidth than a hub, but when I run Iperf after creating a controller based Ethernet switch, I get bandwidth at par with a hub.
Whereas a Flow-accelerated learning switch gives bandwidth in Gbits and is justifiable.
Or is it justifiable by the fact that, since for controller based ethernet switch, we are not installing any flows for the switch and as a result each incoming packet switch receives is sent to the controller, thereby resulting in lower bandwidth?

Can someone justify?
