title: Find/Children vs descendant selector jquery performance differences
body: <p>I am trying to understand why one of the snippets in <a href="http://jsperf.com/jquery-caching-find-methods2/2" rel="nofollow">this jsperf test</a> seems to be significantly slower than the others. </p>
  
  <p>These are the four snippets:</p>
  
  <pre><code>$(".menu-vertical li.selected &gt; ul.static").show().parents().show();
  
  $('ul.root').find('li.selected').children('ul.static').show().parents().show();
  
  $("ul.root li.selected &gt; ul.static").show().parents().show();
  
  $('ul.root li.selected').children('ul.static').show().parents().show();
  </code></pre>
  
  <p>The second one seems to be consistently slower in all browsers and I don't understand why.</p>
