Hi Oliver, my bad, I missed that one. Here is the info:

* Switch with 48x 10G ports and 12x 40G ports was used
* (48) 10G connected nodes were used.
* (24) nodes on each side of the firewall
* Packet per second (PPS) tests were run using 'iperf'
* Bandwidth tests were run using 'nuttcp'
* Parallelization was handled by using pdsh
* Each of the 24 sending nodes ran either:
   iperf3 -c "<target>" -u -A 5 -l 512 -b 0 -t "<duration>" -J
   nuttcp -fparse -l 128k -w1m -T "<duration>" "<target>"
