I would really love it if there was a benchmark around running VMs and containers for something like this. Our dev/test system is all docker containers so that is what we would care about.
I guess it would be hard as there are to many ways to scale out what you run - how many VMs, how many containers, what are you running in them? It would be an interesting benchmark matrix to sort for.
It would be interesting just to see how many containers you could start, run lighttpd and each server a static web page? Maybe 1/2 with the page and 1/2 with an application that builds the page? Who knows...to many variables.
I think we will just by a system when we can and try our workload on it. Oh, well.
