Here are the results from all the possible test combinations between
3VMs that are located on two different physical nodes:
VM1: 10.0.0.5 (node01)
—>localhost 16547.99 10^6bits/sec
—>10.0.0.6 2290.46 10^6bits/sec
—>10.0.0.7 715.94 10^6bits/sec
VM2: 10.0.0.6 (node01)
—>localhost 16484.97 10^6bits/sec
—>10.0.0.5 2346.11 10^6bits/sec
—>10.0.0.7 715.15 10^6bits/sec
VM3: 10.0.0.7 (node02)
—>localhost 22090.21 10^6bits/sec
—>10.0.0.5 483.38 10^6bits/sec
—>10.0.0.6 584.02 10^6bits/sec
Thanks for your time!

Rick and others,
I have installed netperf from the top of trunk and build it with the
--enable-demo option as suggested previously.
This is the output for a test performed on two VMs located at the
same hypervisor:

Both results show a really high bandwidth but I can't get that speed
for file transfers.

Read the names carefully again :)
I was suggesting what I used to do in the past when on a new
OpenStack
install I had this problem.
Indeed, I got the names crossed. Anyway, running netperf is
worthwhile even in a Neutron environment. Run it early. Run it
often
:)
