title: SELECT vs SELECT SQL_NO_CACHE
body: <p>What is the difference in doing:</p>
  
  <pre><code>SELECT * FROM auth_user;
  </code></pre>
  
  <p>Or doing:</p>
  
  <pre><code>SELECT SQL_NO_CACHE * FROM auth_user;
  </code></pre>
  
  <p>I would think that using <code>SQL_NO_CACHE</code> would return the results slower (after the first query), but when I do a <code>SELECT *</code> on a table with about 100 rows, the times are identical, even after repeated queries. Why is that?</p>
