Why does reportviewer 10 render reports so slowly?

Question

I've noticed there's a HUGE difference in the rendering time between reportviewers 9 and 10 in favor of 9. 10 seems to be at least 10 times slower. Has anyone had any experience in tweaking things to fix reportviewer 10? Using Local mode btw.

Thanks.

I'm not sure if its because of the service pack, but now the only reports that render slowly are the ones with subreports in them.
