They really should have run the benchmarks not only in Docker containers but also uncontainerized (as well as one or two KVM VM configurations) as baseline to approximate the overhead imposed by the Docker runtime itself. That would have made the article actually interesting. Would also have been interesting to compare different runtimes (podman,crun,runc) and drivers. I hope the authors follow up with a more fleshed out version because the chosen benchmarks and setup could make for some interesting results with some more rigorous methodology and analysis.
