title: What is the fastest way to find the first record in Rails (ActiveRecord)?
body: <p>I would like to know which method is fastest for return a record.</p>
  
  <pre><code>Class.where(:type =&gt; 4).first
  Class.find(:first, :conditions =&gt; ["type = ?", 4])
  </code></pre>
  
  <p>Is the execution exactly the same?</p>
