However, the application does not have many debugging statist= ics to understand the performance issues. We have added L3fwd as another mo= de/stream to testpmd which provides enough statistics at various levels.

I am wonde= ring if such a patch is helpful for others and if the community would be in= terested in taking a look. Please let me know what you think. 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. > > Thanks, > Honnappa
