Performance of jQuery selector with context

Question

I was reading this article by Brandon Aaron here, about how jquery context may help. So i thought of doing a test of my own. So this is what I did.

It would make sense that it would take longer to use a context (vs. using a selector alone) since internally, the context uses the .find() method, so in essence, all you are really doing is

$('#context').find('#holder');

I mainly see it as an easier way to identify elements in events and iterators where the context changes because

$('.holder', this)

is prettier than

$(this).find('.holder')
