[ovs-discuss] Open vSwitch beats Linux Bridge

[Daniel Tiron]

Hi.

During my research I did some performance tests. In some of your paper
on ovs I read that "Open vSwitch is almost as fast as the native
bridge". Well in my environment ovs beats the Linux Bridge [1].

Do you have any explanation why Open vSwitch, with all it features, is
faster than the "simple" Bridge?

My setup is:
- Host:
	o kernel 2.6.36.1
	o ovs 1.1.0pre2
	o one bridge
- 2 guests:
	o kernel 2.6.36.2
	o QEMU 0.12.4
	o TAP interface (attached to bridge)
- measurement
	o iperf
	o 15 runs
	o 5 minutes each

Thanks,
Daniel

P.S.
Don't get me wrong, I am not complaining ;-)
