Are you sure the traffic isn't being sent to the controller? Depending on your controller, that could slows things down significantly.
I don't think you mentioned what version of OVS you're using. What do you see from "ovs-dpctl show", "ovs-dpctl dump-flows <br>", and "ovs-ofctl dump-flows <br>"? Obviously, replace "<br>" with the name of your bridge. --Justin On Mar 6, 2013, at 11:28 AM, Tmusic <[email protected]> wrote: > Hi, > > Thank you for the quick answer! > I'm actually using it without VM's. > It's an experiment with three "real" computers.
