There is a fair amount of work going on to improve in this area. If you have a large number of established flows (instead of just new flow setups), one thing that might help is to use ovs-vsctl set bridge BR other-config:flow-eviction-threshold=X to set the threshold above your expected number of sustained flows. The default value is 1000. _______________________________________________ discuss mailing list discuss@openvswitch.org http://openvswitch.org/mailman/listinfo/discuss
