On: Ruby Web Applications Without Rails

[fortytw2]

It's been a while since I last used rails, but something about

> A "Hello World!" in Rails takes about 1.13 seconds to render

strikes me as most definitely incorrect... If not, I'm shocked.

That's for a cold start. Once the application is initialized, it becomes way faster.

If one uses Unicorn in production there's no such thing as a `cold start` Ruby is not the JVM lest you run JRuby or Rubinius ofc :-)

I'm not sure that's accurate - most of Rails is lazily loaded now I believe, specifically to reduce start-up time. You can use a different strategy in production of course.

By default, Rails only does lazy loading in development mode.
