Subject: vxlan gro problem ?
Date: Wed, 8 Oct 2014 16:46:58 +0800 [thread overview]
Message-ID: <5434FA02.8070608@huawei.com> (raw)
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 ?
