jQuery Template Plugin Vs Native DOM Elm Creation

Benchmark created by newbreedofgeek on

Description

A Speed test to check the difference in render time when using a) jQuery Template Plugin - http://api.jquery.com/jQuery.template/ b) Native javascript DOM element creation

to loop through an array of objects and render the output.

I like the template binding flexibly that the Template plugin gives but as you can see it's much much slower than native DOM element creation and binding. So good for website use, but probably not so good for low end browser engines like those used in STB and mobile (which is why I needed it for)
