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).

Currently supported LS2088A, LS1088A, soon LX2160A (all with
ARM64 cores).

I should have an answer for this early next week and will
get back to you.
Thanks,
