There was always a mess and confusion around the scaling abilities of Rails.
We’re hearing this from multiple sources: After nearly two years of high profile scaling problems, Twitter is planning to abandon Ruby on Rails as their web framework and start from scratch with PHP or Java (another solution is to stick with the Ruby language and move away from the Rails framework).
.. as it was written yesterday on Techcrunch.
On the other hand, David Heinemeier Hansson (creator of Ruby On Rails) wrote a post on Loud Thinking (his personal Blog) about the scaling opportunities of the framework.
Well, I am about to dig deeper into this very exciting question and share my experiences.
UPDATE: Just got noticed by Arnold Funken on Twitter:
