Not to be a stickler, but the only fair benchmark would be to select the most recent stable version of each. Doing so is fairly easy with docker I would think, if you don't wish to modify your system.

I wouldn't say you are a stickler. But the most productive addition to the discussion would be to do the benchmark as you see fit and then show us the results.

Very fair feedback. I'll do so once I'm at a machine!
