For now, if you want a fast language with the beauty and productivity of Ruby, check out Elixir [0] and its web framework, Phoenix [1]. I've been using Phoenix for a year, and it's the first framework that I've actually liked more over time. And I've been a web developer for a decade. With its recent 1.0 release, Phoenix is gaining a lot of momentum.
If you want some idea of the performance differences between Phoenix and Rails, see [2] and [3].
