It's still clickbaity, but the title implies a comparison between a very lightweight VM and a heavy-weight container (presumably a container based on a full Linux distro). You could imagine an analogous article about a tiny house titled "my house is smaller than your apartment".

- turkishmonky 4y agoNot to mention, in the paper, the lightvm only had an advantage on boot times. Menory usage was marginally worse than docker, even with the unikernel, and debian on lightvm was drastically worse for cpu usage than docker (the unikernel cpu usage was neck and neck with the debian docker contaner). I could see it being an improvement over other VM control planes, but docker still wins in performance for any equivalant comparisons.
