I've spent more than 2 seconds on Google for this topic. This StackOverflow post[1] was actually very informative. See the answer by Jörg W Mittag, specifically this quote:
>>In several interviews, the Twitter developers have pointed out that Ruby on Rails was not responsible for their scaling problems. On the contrary, only the maintainability of Ruby made it possible to do such large-scale architectural changes to fix their scaling problems.
Then again, that seems to have been written in 2010. I'm sure things changed since then.
