Hello,
        Performance of L3fwd example application is one of the key

benchmarks in DPDK. However, the application does not have many
debugging statistics to understand the performance issues. 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.

There is more work to be done to get it to upstreamable state. I am

wondering if such a patch is helpful for others and if the community would
be interested 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 Jerin. We will explore that.

I agree it is dangerous to rely too much on testpmd for everything.
Please tell us what in testpmd could be useful out of it.
