The linked page mentions an artificial test case that gets a large benefit, but shows an inconclusive result for the more general page load benchmark cited. There are definitely image-heavy real-world sites out there, such as <http://cuteoverload.com> or flickr.com photostream pages. (2) Did you do any testing of time to first paint in addition to page load time? Cheers, Maciej
