Revision 32 of this benchmark created on

Description

Fine tuning the DOM method to yield better performance for this particular synthetic test. (alternate method without cloning)

Preparation HTML

<div id="main_node"></div>
<script>
  var parent = document.getElementById('main_node'),
      fragment = document.createDocumentFragment();
</script>

Setup

document.getElementById('main_node').innerHTML = '';
    var innerHTMLDOM = '<div>';
    for (var i=0; i<1000; i++) {
      innerHTMLDOM += '<div></div>';
    }
    innerHTMLDOM += '</div>';

Teardown


    document.getElementById('main_node').innerHTML = '';
