</thread> Turns out I do get 1Gbps from another machine to the opi5+. Strange thing is the machine I was testing with actually does 1Gbps with another server. Sorry for the noise.

Hi, Like the topic says, both NICs are underperforming, they are connected to a Gb switch which I use and benched with other machines, neither iperf nor iperf3 (threaded and not threaded) go higher than 700Mbps. Another server plugged on the same switch reaches Gb steadily. I applied CPU affinity so both IRQ's are handled by the A76 cores but it makes no difference.
