Google has a series of articles and videos on making the web faster. Some folks over on reddit have already pointed out the contradictions on css selectors as well as some “eating your own dogfood” issues with Google’s implementation of the examples in their primary site. I think a few of their tips fall short, but it’s a decent introduction to web performance.
The most controversial idea on the site for me is telling webmasters to drop “optional” close tags in HTML. Since HTML is based on SGML, it is not invalid to leave off certain tags, but I think it’s sloppy. In XHTML, based on XML, it’s invalid to leave an element open.
