Ok, other than purchasing a beast of a machine to improve performance...

I've got a Javascript/AJAX driven web app that was written utilizing jQuery in order to speed up inital development time. I'm finding that from a performance perspective, I'm ready to begin supplanting piece by piece to improve the code efficiency.

One Example...

<http://jsperf.com/innerhtml-vs-jquery>

I moved away from using **`$(selector).text()`** in active areas to naitive DOM access with **`getElementById(id).innerHTML`** 

I'm a little bit at a loss as to where to go next in terms of getting the most bang for my buck, **what are some glaring areas where utilizing jQuery causes you to take a performance hit (outside load times)?**
