You are using the SKB mode, not the zero-copy mode that will give you higher numbers. Somewhere around 20 Mpps if you run a new kernel. > One big issue is this command "sudo ./xdpsock -t -i enp1s0f0 -N -z" > Fails with: > samples/bpf/xdpsock_user.c:xsk_configure_socket:322: errno: > 95/"Operation not supported" What driver are you using?

The virtual function (vf) driver of x710/i40e does not but the physical function driver does. > Is there a guide or README I should read on how to try to achieve > numbers like theirs? > > If there is not a guide, would it be helpful if I wrote one?
