Who'd have thought that an additional layer of abstraction has a small impact on performance. Nothing else in computers work that way.

Great - you've made a hypothesis using your intuition. It seems like it's probably true. The science part is then checking that this it actually is, rather than just assuming, which is what this paper is.

No hypothesis or intuition at play. I've read some of the many articles covering the performance impact of using docker on various metrics. Useful metrics, unlike an electric bill.

Huh? Electric bill is the #1 useful metric for any workload at scale. If you're small, maybe human administration costs dominate that, but otherwise it's virtually guaranteed to be the primary operating cost.

I guess so, but if it matters that means you have hardware and I hate having to manage hardware. So I guess that colors my opinion on the matter.

Your criticism would make sense if the title of the article was "Does Docker affect energy consumption?".

However, the article is titled "How does Docker effect energy consumption."

It is about an experiment which aims to quantify the impact on performance, which is quite interesting.
