Assuming that the goal is to host a single "App" on the bare metal server, these tests results are indeed interesting. Another interesting result -- not addressed in the paper -- is to see how many small Apps that the container approach can support versus the vitalization approach can support. While hosting many Apps/VMs, not having to run the OS multiple times is one of the advantages that the Docker approach provides and it would be interesting to quantify the performance implications.
