Number of flows and incoming traffic distribution is really high. Number of rules is +0.5 million and possible number of IP of incoming traffic is also in millions. But right now I am sending same pcap file to all interfaces using PKTGEN. There is no slow path as it is OVS-DPDK, everything in userspace.

Is the slow path thread ovs-vswitchd maxed out? _______________________________________________ discuss mailing list [email protected] https://mail.openvswitch.org/mailman/listinfo/ovs-discuss
