Hello Ben,
some feedback regarding the latency issue. We upgraded the kernel module
and userspace to version 2.3
We now have around 30 - 50 flows, this is a huge improvement! The
TCP_CRR numbers are looking much better now.
Thanks for the work you put in this!
Do you have any numbers to share comparing the Linux bridge and
openvswitch regarding TCP_RR and TCP_CRR performance?
Thank you in advance!
Cheers
Chris

How can I find out what version that is? I am not familiar with how
OpenStack is distributed.

Hi
It looks like it's the one which comes with OpenStack:
# modinfo openvswitch

Linux 2.6.32 doesn't come with an openvswitch kernel module, so what
version
of the kernel module do you have? Some performance improvements will
only
come with a sufficiently new kernel module.
