Start time and memory usage are atrocious. This is heavy plenty enough. > To clone and run one sample app I needed to upgrade XCode, upgrade the command line tools for XCode (>6GB in total), install a new Ruby version and bundler and then bundle install in the sample app... > That whole exercise took hours. Just because you do sh&t with even heavier and crazier tools doesn't change the fact that JVM is heavy. You just look in wrong direction, that's all. > I run at least 5 JVM processes on my 2012 MacBook Pro with 8GB of memory. This is all day, every day. I would never have tried to start 5 Rails apps at the same time. Wow, what an accomplishment. I run twice that number of Python web applications on a VPS that has 768MB RAM, and the server hosts also other things. You just don't have the right perspective.
