I think you're conflating his separate points:
"What you -are- benchmarking is namespaces, cgroups, CoW filesystems and your underlying hardware."
"Also worth nothing that compute benchmarks will be absolutely worthless as they -will- be 1:1 native performance"
Whether it's accurate or not, people associate Docker with the functionality if facilitates. (i.e., cgroups, namespaces, etc.) so i think it's valid to show the performance impact of running an application from within docker.
Based on my data, they're not 1:1 native performance. I suggest you consider the data before dismissing it.
