Yes, using the pmd-stats-show command I can see that about half the traffic
has to go to the OF Classifier, and if I watch the "ovs-appctl dpctl/show"
the number of flows in the dpctl is changing very rapidly, is there a way to
increase the time flows stick in the dpctl?

By slow path I mean the ofproto classifier:
