title: Ruby 1.8.7 versus Ruby 1.9+ performance
body: <p>Recently I have been tasked with working on a fairly high volume Rails api (5k requests a second at peak).</p>
  
  <p>Prior to this I've spent most of my coding efforts on Java applications, I'm just new to the world of Ruby/Rails.</p>
  
  <p>At home I've been using the latest versions of Ruby/Rails to develop some small applications and get a feel for the language and framework.</p>
  
  <p>The Rails application at work is built on Ruby 1.8.7 and Rails 2.3.16 and to me it seems quite old and there are quite a few syntax and new features missing compared with the current versions I use at home.  I prefer the newer versions of ruby and rails.</p>
  
  <p>I raised with my team about wanting to upgrade to newer/latest versions but I was told that newer versions of Ruby aren't 'production' ready.  Sadly due to my inexperience with Ruby I'm not really in a position to dispute this.</p>
  
  <p>Any good articles/metrics showing either same or better performance with newer Ruby/Rails versions? Personally I would expect newer iterations of a language/framework to have better performance.</p>
