When many regions are used on the same same page, they are slowing the page down considerably.

Check http://sourcefabric.github.com/BookJS/test.html for a simple demo. 

Check http://sourcefabric.github.com/BookJS/test2.html for a demo of lots of flows.

Check http://sourcefabric.github.com/BookJS/test3.html for a demo of long flows.
