That's a pretty exact number ;-)

Is this a measurement from metrics collected from a production
enviroment, or were you using a synthetic benchmark?

If it was the latter, would you be able to share the tooling?

I'm looking at extending the fio net engine with sockmap support, so
that we can have a reference benchmark. It would be helpful to see which
sockmap setup scenarios are worth focusing on.

Thanks,
