Ruby 2.1.0 performance in Rails tests

Ruby 2.1.0 introduced many performance improvements.

Ruby 2.1.0 (released on the very end of previous year) introduced many performance improvements, about which you can read here https://www.ruby-lang.org/en/news/2013/12/25/ruby-2-1-0-is-released/. In fact, Ruby core developer Aman Gupta published earlier today nice post about how GC works now.

How much faster can Ruby 2.1 be in day-to-day workflow? I've decided to give it a try and checked on one of our apps with ~600 tests and 1600 assertions.
