Wanted to know if this is expected before investing more into this. The Y a= xis numbers in all the following charts (from Grafana) are MPPS/core which = means how many cycles per packet the CPU invest. Bigger MPPS/core means les= s CPU cycles to send packet. Labeles: trex-08 (XL710) trex-09 (X710) trex-07 (mlx5) kiwi02 (ixgbe) Grafanna charts can be seen here: (we can't share pointers to Grafanna) https://snag.gy/wGYp3c.jpg More information on the tests and setups can be found in this document https://trex-tgn.cisco.com/trex/doc/trex_analytics.html link to the project https://github.com/cisco-system-traffic-generator/trex-core Thanks, Hanoh
