How to test dpdk feature

currently i enable dpdk feature on suricata 7.0 in my project, is there any dpdk performance testcase in suricata project ?

Many folks use a traffic generator to test performance, so for example T-Rex is one option to test it.

thanks for your reply, i tried t-rex and dperf, all works.
currently there is another problem , the suricata has a large drop rate

Can you be more specific? What is your hardware and software (config) setup, what is the traffic, what are your outputs (maybe even compared to AF-Packet)?

One of the usual mistakes is that people do not set CPU affinity. Have you done it? Then you may try to increase also DPDK properties as mempool size and similar.

i list the information here
