We hae pushed changes which should significantly improve performance on larger queries. I'm not quite sure about the 100% cpu question as we have not been able to reproduce this but it could simply have been the control spinning through the rendering of a very large cellset. Please contact me via my blog at http://andrewwiles.spaces.live.com if you still see a problem. We are very keen to work with developers at the moment to refine the controls.
