Welcome to the world of VML. 

Seriously, I doubt there's going to be much you can do in OL to help
yourself here: IE's rendering is much much slower than FF. The order of
slowness is probably something like:

 Safari 3.1 (SVG) > FF3 (SVG) / Opera 9.5 SVG > Opera 9.0 SVG > FF2 SVG > 
 IE 7 VML > IE 6 VML  

I would not be at all surprised to find out that complex VML rendering
is too slow to be usable for many people.
