I have a 4.21 QoS Core with 4 RX + 4 TX and detected no regression. Could you please share the iperf cmds you are using in order for me to reproduce in my side? @stmmac users: It would be great if people that have a setup could also perform teh same iperf test in order to clean in up for everyone. Thanks, Joao
