Revision 20 of this benchmark created on

Preparation HTML

<div id='sample'>
  <h1 id='title'>Title</h1>
  <h2 id='subtitle'>by</h2>
  <div id='content'>
  </div>
</div>
<script>
function add(node,arr) { for(var i=0;i<arr.length;i++) node.appendChild(arr[i]); return node; }
function t(txt) {return document.createTextNode(txt);}
function f() { return add(document.createDocumentFragment(), arguments); }
function e(name, attrs) {
   var el=document.createElement(name);
   if(attrs) for(var prop in attrs) el.setAttribute(prop, attrs[prop]);
   return function() { return add(el,arguments); }
}
</script>

Setup

var colors = ["red", "yellow", "green", "cyan", "blue", "magenta"];

Teardown

        e("h2",{id:"subtitle"})(t("by")),
        e("div",{id:"content"})()
