I've performed some further experiments. I reran the netperf and iperf
tests while using the iptraf tool to validate the netperf and iperf
results.
Iptraf is within a few percent of netperf and iperf in all cases except
iperf tcp stream. Iperf tcp stream shows 9.4 Gb/s, iptraf shows 2.7
Gb/s

See the above three log files, 2 with iperf and 1 with netperf.
iperf is equivalent between 3.11.0-15-generic and 3.13.6 upstream kernel
when running point to point (no switch). TCP stream is as expected.
UDP stream is poor in both cases.
netstat results are significantly different than iperf
