Hi, Mikhail Isachenkov
The server and client on the same machine. You can see from the below detail, the AVG of course do have less value

Hi, Maxim Konovalov:
Yes, this host has no ADQ-capable cards, the server use Mellanox NIC, if use ADQ-capable cards, the latency improvement will be 40%
Thanks

Hi, Maxim Dounin:
Thanks for your reply, this server is random selected, we just do BPF and no-BPF test, I think the latency based on server configuration, not related with BPF patch, also the NIC
of the server is Mellanox, not ADQ capable hardware , we will do more test
Thanks
