Description
I used gXDP to implement NAT function. Bandwidth testing on VM，gXDP is 1.6Gbit/s and lvs is 5.6 Gbit/s(DPDK is 5.9Gbit/s). (**linux kernel version is 4.18**)
But when I use gXDP on docker network, the bandwidth can reach 5.9Gbit/s.
Does gXDP depend on NIC configuration?
Plz help me.
Thx🙏
