Netflix runs Java heavily on the backend to scale their platform. Twitter ditched Ruby on Rails and moved to JVM (Sala) for the same reasons. Any benchmark comparison for programming language performs will show Java beating Ruby on Rails, Python etc by huge margin.

Also, isn't Netflix actually using Python instead of Rails?

The main thing Java beats other langs in by a huge margin is memory consumption.
