[ovs-discuss] About ovs performance on 'worst case scenario'

[Jose A. Posada]

Thanks a lot Justin, I need to use the OVS like a simple L2 switch with VLAN. And with version 1.9.0, I get a poor performance in my scenario. t's great that you have worked to improve and correct this deficiency. I had to use the Linux bridge, with which I’m giving up many additional features that get using OVS.

It should be improved in 1.10, but it will likely not be at the level you want. We're in the process of adding wildcarding to the kernel, and depending on your flow table and configuration, will yield significant performance benefits. If you are just doing normal L2 learning, it should be very close to the Linux bridge's performance. The patch that glues the new userspace and kernel logic will be going out early next week. Once that's out, you can test it for yourself. We're aiming to have the changes land in 1.11.

Hello,

I have been reading your discuss, it's clear to me that the module kernel isn't optimum with many small flows and packet with different UDP/TCP ports for OVS versions: 1.0, 1.4.3 and 1.9.

I think that OVS is a very useful tool and I have used it in my core network where there is a lot of traffic and varied traffic too (tcp, udp, few huge flow and many small flows at the same time).

Then, my question is: does 1.10.0 version fix it or improve it?

Or, is there another solution for that?

Best Regards

Jose
