performance degraded for IE 7/8

I got excited that 1.8.1 and 1.8.2 were targeting performance improvements for older browsers but I have found the opposite to be true. I've lost an entire second on one of my product pages.

Running IE's F12 tools, it seems certain routines are being called A LOT. RegExp.test was executed 211,705 times! Array.push was called 180,966 times!. getAttribute was called 143,161! And two anonymous functions were called over 200,000 times. I'm shocked, not sure what has changed because the worst offender on the old version was only called 69,975 times.

We really need a test case. It's not possible to know what the problem is with some numbers you've collected, without seeing the code that produced them.
