We have added L3fwd as another mode/stream to testpmd which provides enough statistics at various levels. This has allowed us to debug the performance issues effectively.

We are using app/proc-info/ to attach and analyze the performance.
That helps to analyze the unmodified application. I think, if
something is missing in proc-info app, in my opinion it is better to
enhance proc-info so that it can help other third-party applications.

Just my 2c.
