One side effect of this change that I am a bit concerned about is performance of configuration changes. In particular, it looks like removing a port requires copying the entire configuration and that removing N ports requires copying the entire configuration N times. Can you try a few experiments with configurations that have many ports, maybe 500 or 1000, and see how long it takes to remove several of them? _______________________________________________ dev mailing list dev@openvswitch.org http://openvswitch.org/mailman/listinfo/dev
