A simple comparison of Dom selection vs Jquery selection[1]

When selecting one DIV by id, I'm consistently getting:

DOM - 0.08ish ms

Jquery - 0.2ish ms

I do have an app where every millisecond is critical. For this app I'm using raw dom selectors. However, most of the time, the convenience of jquery selectors outweigh these performance gains.
