Admittedly, this is based on Windows Task Manager, which isn't über-reliable. Also, I only stored simple, 12-character strings (complex objects may be different). Unfortunately, IE slows down exponentially when adding or removing properties from many elements at once. It takes .5 seconds to add a simple property to 1,000 elements... and 51 seconds for 10,000 divs. In some quick tests, Firefox shows almost no difference when adding / removing properties on 50,000 elements.
