jQuery performance in IE7

[Eli Cochran]

Lovemore,
There are some interesting performance comparisons here:
	http://docs.jquery.com/Release:jQuery_1.3#Performance

They show that the JS engine in FF are significantly more performant  
than IE.

The good news is that things get better with jQuery 1.3.

I'll try to take a look at your actual code a little later in the day  
to see if there are specific things that you might do that could  
improve the speed of your code.
