Guidance Required to Improve Throughput on ConnectX-7 (1x400G) with DPDK v23.07

[Ayshathul Thuhara]

Dear Team,
I hope this message finds you well.
I am currently performing testing on ConnectX-7 with 1x400G hardware using DPDK v23.07. However, I am unable to achieve data transfer rates beyond 10 Gbps. While reviewing the DPDK mailing list, I came across your previous responses in the related discussion (https://mails.dpdk.org/archives/users/2024-July/007767.html), where you mentioned achieving throughput of around 250 Gbps and above.
Could you kindly advise on the configuration changes or optimizations required to improve throughput in this setup?
For reference, I am using an OSFP loopback module for testing, where the same port is used for both transmission and reception (single-port loopback setup).
CX-7 Firmware: 28.45.1200
CPU : Intel(R) Core(TM) i7-14700
Command used : sudo ./build/app/dpdk-testpmd -a 01:00.0 -- -i
I would greatly appreciate your guidance.
Thank you in advance, and I look forward to your response.
Thanks and regards,
Ayshathul Thuhara
