Nice progress indeed. They seems to get 33 Mpps in RX on 1 core with 40Gbps i40e Intel NIC: > One for Tx/Rx and one for the user space application.
The TX direction is much slower, hitting only 19.6Mpps. It's not clear from the thread whether CPU is bottleneck or something else. This correlates a lot with what Ilias and I try to achieve using mediated devices. I believe we can get better performance at a cost of exposing TX/RX rings and NIC HW to userspace. I'm going to get access to a pair of i40e NICs soon, so we'll update about performance with mediated devices hopefully in couple of weeks.
