Dear all,

I have noticed that the performance reports on the official DPDK website predominantly use l3fwd, while we typically utilize pktgen. Out of curiosity, I attempted to replicate the experiments from the performance reports. However, I encountered some issues, as shown in the attached image.

I ran pktgen on PC1 and l3fwd on PC2. After establishing the connection, I entered the command str on pktgen. It appears that pktgen is able to send and receive packets normally, but there is no output from l3fwd. Based on my understanding, l3fwd should produce some output, correct?

Could you please share how you usually conduct these tests for your performance reports?

Thank you for your assistance.

Best regards,
Howard Wang

Hi Howard, 
   You can check out the performance test report. In most cases, the report will include all setup details (including the command line).
