on last test i see iperf3 has ~30%cpu load and also ksoftirqd (using debian buster), so i tried opening server on my Laptop and running iperf -c on BPI-R2 with similar result

in dmesg of both devices only DSA-Messages (nonfatal error -95 setting MTU on port) because of missing port_change_mtu callback. here i got a patch, but had not yet time to setup environment for testing jumbo-frames too. But this just as side-note
