Subject: [dpdk-users] What is TCP read performance by using DPDK?
Date: Tue, 23 Mar 2021 23:06:46 +0000	[thread overview]

Hi experts,

1.
Did you use DPDK to implement TCP server (read TCP data and then discard)?

If yes, what is the max performance you can achieve on Intel X710 10Gbps NIC?
(I am not using VPP TCP stack)

2.
My feeling is that DPDK can only be used for layer 3.
For layer 4, DPDK can only look at TCP header.
Once DPDK look into TCP payload, performance drop down drastically.

3.
If DPDK can only be used for layer 3, Linux eBPF is another choice.
