    This is a fork of <a href="http://jsfiddle.net/jashkenas/CGSd5/" target="_top">jashkenas's Ember/Backbone</a> benchmark to include Vue.js. Note that this is just a simple benchmark: you wouldn't be doing this in an actual app.
</p>

<p>The original fork was clocking the loops synchronously which was not accurate. This fork fixes that, and also gives a 300ms pause before clock starts to offset...
