Question about kni performance

[455434913]

Hello, I ran the KNI example from DPDK version 19.11 and performed a ping 
latency test from another machine. I found that after running KNI, the latency 
increased by over 100 times—from the original 0.05 ms to 7 ms, which is 
unacceptable for my use case. My network card is an mlx5 with a specification 
of 1000 Gbps. Is this performance degradation within normal parameters? What 
methods can be used to optimize it?
