The problem isn't really "the benchmark is flawed", the problem is that most of us seem to wish for data that tells us more than it can, magical wishful thinking on our part - Will the application I haven't designed yet be faster, and scale better, and be completed by us faster, if we write it in X or Y? :-)
But you're right, deployment isn't a totally solved problem. Unless you just use Heroku: http://devcenter.heroku.com/articles/node-js
I mean, Node was created in 2009. I don't see anybody bragging about how easy it is to deploy yet; just that it's fast and easy to understand.
