After changing its MTU from 1500 (default) to 9000, I performed iperf and I got a result around 2.70Gbps, though it seems that the result is not stable, sometimes the value going down to 2.30Gbps or lower.
I don't know why but manually assining iperf processes to a specific core (taskset -c 5 iperf -s, for example) seems to offer better and stable results that is 3.00Gbps.
Hi!
I also tested aquantia cards and came to the result, that the driver has poor performance, i.e. missing offloading capabilities. I also have an tehuti tn4xxx network card. This one gave me about 9GBit/s single threaded iperf3 performance, a lot better. Even vlan offloading works.
If you want to give it a try, you have define RX_REUSE_PAGES in tn40.h
