SYMPTOMS

When you use Internet Explorer 7 to browse to a SharePoint 2010 list that is set to display a large number (200 or more) of items on a single page, CPU usage may increase significantly, and navigation performance may be degraded when the cursor hovers over list items.

CAUSE

This is a known issue with the way Internet Explorer 7 implements the :hover pseudo-class in CSS.
