Hi all, recently Linux 3.14 has been released and I find the networking has added udp gro and vxlan gro funtion, then I use the redhat 7.0(there is also add this funtion) to test, I use kernel vxlan module and create a vxlan device then attach the device to ovs bridge , the configure as follow: root@25:~$ ip link 15: vxlan0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1450 qdisc noqueue master ovs-system state UNKNOWN mode DEFAULT link/ether be:e1:ae:3d:8b:f2 brd ff:ff:ff:ff:ff:ff 16: vnet0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1400 qdisc mq master ovs-system state UNKNOWN mode DEFAULT qlen 5000 root@25:~$ ovs-vsctl show aa1294f3-9952-4393-b2b5-54e9a6eb76ee Bridge ovs-vx Port ovs-vx Interface ovs-vx type: internal Port "vnet0" Interface "vnet0" Port "vxlan0" Interface "vxlan0" ovs_version: "2.0.2" vnet0 is a vm backend device, and the end is the same configuration. then I use netperf to test throughput in vm (netperf -H **** -t TCP_STREAM -l 10 -- -m 1460), the result is 3-4 Gbit/sec, the improvement is not obvious, and I also confused there is no aggregation packets (length > mtu) in the end vm. so I want to know what wrong ? or how to test the function ? -- To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
