Papervision - add planes?

Hi,
Using the newest release of papervision, I’m trying to use a for loop to add 2,000 black planes to my stage but it keeps timing out. It’s incredibly slow to render, even if I use 100 planes (it DOES work with 100 planes).
I know papervision can handle lots of geometry, as I’ve seen complex models imported and even animated.
What is the deal here? And is there a way to just make one plane and then have 2,000 instances of it rather than creating 2,000 new planes?
