I would expect very little if any measurable effect on forwarding performance. At least for the counters that I moved to the stats segment: vpp was already maintaining them. Not much changed.

Documentation would be very appreciated Any idea how much more evolving it’s going to do? Is there any impact on performance of vector processing from using it?

Yes. Very much so. > Has anyone written anything here that we can use? Not yet. The feature is somewhat experimental. And there are still a few bits missing with regards to the client side. On the VPP side the only thing requires is giving the existing counter a name, so that's pretty minimal. Let me try to write something down while we're evolving the feature (I'd very much like to hear from people who are interested in using the new stats infra), and then that can be used as a base for writing user documentation.
