Yahoo!’s got a very interesting page on web performance which I think is still crucial in our fast-speed Internet and fast number-crunching CPUs. Here’s a description and some of their “Rules”.

Yahoo!’s Exceptional Performance team evangelizes best practices for improving web performance. They conduct research, build tools, write articles and blogs, and speak at conferences. Their best practices center around the rules for high performance web sites.
