Normally I'd agree about 20s being too long. But I'm specifically talking about users on slow links. They often know they don't have a first class connection out, and have established a different set of expectations. If your site is actually good enough to be one the users return to (and who here wants to build a site where that's not the case?), they all appreciate the site loading very fast the next time.
