Which jQuery selector is more efficient with .find()

Does the tag name hurt or help?

1) $content.find('[name=foo]')

or

2) $content.find('input[name=foo]')

I wrote a quick JSPerf test, it's actually almost the same.

Both are pretty slow (jQuery is quite slow anyway).

I tested the $.find() method two weeks ago. It's a good habit to use it, it's pretty efficient.

Before testing it, I'd say the second should perform better since it can take advantage of DOM method getElementsByTagName. This is a first level filter that should improve a little the performance.

Probably it won't be noticiable unless the page is complex enough
