I ran the benchmark multiple times and I got very consistent results. I know that doesn't eliminate the VM factor, but it certainly minimizes it.

Also, this test wasn't meant to be scientific. I'm not selling docker, postgres or digital ocean, just satisfying a personal curiosity.

Benchmarks are touchy things in general, I understand that.

I published the results and I'd love to see someone publish conflicting results, or verify them. I've tried to be as transparent as possible.
