HI Foucault,
do you have MTU 9000 everywhere? Even tap interface outside and inside
of VM?

Hi there,
We are actually running new benchmarks on Opencontrail 2.21.x version.
The maximum throughput we can get is :
- ~6Gb/s in "half duplex" from VM A -> VM B or VM B -> VM A
- ~3.5Gb/s in "full duplex" in a VM A <-> VM B pattern
Tests are run with Iperf on Ubuntu 14.04, computes are also on Ubuntu
14.04, kernel 3.13.0-83-generic
Does anyone have run similar tests and may have results to share ?
If anyone have dig on optimizations on a system level that could
improve those results, I'd love some informations.
Thanks,
Foucault
