I was thinking about whipping together a perfJS for the curry function and putting it in the post but ended up not... I might make one and post it back here.

UPDATE: I made this jsperf: http://jsperf.com/curry-function

There might be better things to test, but the results were actually unexpected. Currying "manually" with nested functions is actually slower than using my "curry" function.

As I mentioned in my post, if you are touching the DOM at all, I really doubt you will see much of a performance hit from using this...
