I have two setups for performance measurem= ent, which are almost identical, the only difference is that one setup has = i40e driven 10G NICs and the other one has ixgbe driven 10G NICs. I have MoonGen for packet generating, and testPMD to reflect the traffic. T= he measurement results are much higher with the ixgbe-driven card. It's abo= ut +20% with smaller packet sizes, and more than +40% with bigger packet si= zes. Does anyone have any idea what can cause this? Is there any significant dif= ference between the mentioned drivers? Thanks and Regards, J=E1nos
