We have some preliminary perf data that doesn't look great, but we hope to improve it :) On a LS2088A with A72 cores @2GHz (numbers in Mpps): 1core 8cores ------------------------------------------------------------------------- XDP_DROP (no touching data) 5.68 29.6 (linerate) XDP_DROP (xdp1 sample) 3.46 25.18 XDP_TX(xdp2 sample) 1.71 13.26 For comparison, plain IP forwarding through the stack is currently around 0.5Mpps (1c) / 3.8Mpps (8c). > > Also what boards (and arch's) are using this dpaa2-eth driver? Currently supported LS2088A, LS1088A, soon LX2160A (all with ARM64 cores). > Any devel board I can buy? I should have an answer for this early next week and will get back to you.
