The benchmark performance tests can be run with Onload using the Onload kernel bypass. To do this add onload to the start of each command line.

Run the net-server application on system-1:

[system-1]# pkill -f netserver
[system-1]# onload taskset -c 1 netserver

Run the netperf application on system-2:

[system-2]# onload taskset -c 1 \
   netperf -t TCP_RR -H <system1-ip> -l 10 -- -r 32
