You should either
- run netperf using test addresses outside of the
10.X.0.0/16 range (in our setup, primary addresses of
Polygraph machines are outside that range),
- run netperf before enabling dummynet delays.
Netperf ties response time and throughput and, hence, cannot show
meaningful throughput measurements in environments with packet delays.
