Am I correct in assuming that the relevant characteristic of Node and Go is high concurrency? If I'm not mistaken, Ruby can have that too, if you use something like Puma or Thin rather than Unicorn.

Python may be on the wrong side of this, though, as long as Gunicorn is the de-facto standard WSGI server for Python apps on Heroku.

Not just concurrency but also boot time.

On my Production Rails app `time rails s` takes about 0m2.273s for me (Rails 4, Ruby 2.1.0). Not an insanely fast boot time, but nothing to lose sleep over.

Roughly how many models and controllers are in the app?
