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!
