Hi, I’m looking into how this is possible
http://opencontrail.org/evaluating-opencontrail-virtual-router-performance/ achieving 10G line rate between two VMs on different hypervisors over a tunnel using MTU 1500 in the VMs. I see (at least) two possible issues with my setup: - Packets egressing openvswitch over a gre tunnel is segmented to 1500 bytes. If I configure mtu 9000 in the VM, the packets are segmented to 9000 bytes on the gre tunnel - in any case tcpdump in the sending VM shows packet sizes of 62636 bytes - strange ? - I’m having doubts about the pps performance of virtio and Xens netback/netfront - Anybody experienced significant difference between these? or even tried the dpdk drivers ? I’m using debian with kernel 3.12.13 and openvswitch 2.1 Thanks Regards Kristoffer _______________________________________________ discuss mailing list discuss@openvswitch.org http://openvswitch.org/mailman/listinfo/discuss
