GitHub - noahgibbs/rails_ruby_bench: A Rails-based benchmark for Ruby development
Rails Ruby Bench (aka RRB) is a Discourse-based benchmark to measure the speed of the Ruby language. It can incidentally be used to measure the speed of a number of other things. RRB is a "Real World" benchmark, in the sense of running a large Rails app in a concurrent configuration with a lot of complexity and variation in what it does. That makes it wonderful for measuring end-to-end effects of

Ruby 3x3: Ruby 3 will be 3 times faster â€” Engineering Blog
At RubyConf 2015 in San Antonio, Yukihiro "Matz" Matsumoto announced Ruby 3x3. The goal of Ruby 3x3 is to make Ruby 3 be 3 times faster than Ruby 2. At AppFolio, we think this is awesome and want to help. [Update: watch Matz's keynote ] We have been using Ruby for the past nine years. Like most people, we initially came to Ruby via Rails.

Rubyists: Just use double-quoted strings. | Viget
TL;DR If you've written Ruby, you've heard it before: Use single quoted strings unless you need string interpolation. It makes sense, right? When I instantiate strings using double quotes, the Ruby intepreter has to do extra work to figure out if it needs to perform interpolation. Since extra work means reduced performance, it seems reasonable to avoid double-quoted instantiation unless it's a nec
