title: Unicorn web server questions
body: <p>I recently discovered this line in my <code>Gemfile</code>:</p>
  
  <pre><code># Use unicorn as the app server
  # gem 'unicorn'
  </code></pre>
  
  <p>I have 2 questions. </p>
  
  <ol>
  <li><p>Why would I want to use unicorn over the default <code>WEBrick</code>? </p></li>
  <li><p>How do I get it to work? I uncommented that line, ran <code>bundle install</code> and then <code>rails server</code> and it still booted up <code>WEBrick</code></p></li>
  </ol>
