Thank you for your reply, Ben. Some heads up, we changed our flow idle_timeout to 300, then ran the test again, and got around 6000 packet-in per second. After some investigation, it turns out that most of the ovs-vswitchd CPU cycles are consumed by add flow, like classifier_rule_overlaps(), minif

Hi everyone, I am currently running tests to test packet-in performance of OVS (ovs-2.0.1). By starting up a large number of different connections simultaneously, causing a bunch of packet-in messages sent to the controller. It turns out that OVS can only handle about 3000 packet-in messages per s
