Hi! I want to make sure I did everything right to make my XDP program (simple forwarding with bpf_redirect_map) as fast as possible. Is following advices and gotchas from this: https://www.mail-archive.com/netdev@xxxxxxxxxxxxxxx/msg184139.html enough or are there some additional/newer recommendations? I managed to get near line-rate on my Intel X520s (on Ryzen 3700X and one queue/CPU), but not quite 14.88 Mpps so I was wondering is there something else to speed things up even more. Also, are there any recommended settings/tweaks for bidirectional forwarding? I suppose there would be a drop in performance compared to single direction, but has anyone done any benchmarks? Regards, Denis
