You've got to check your pages with YSlow as well. People often confront me with these 15% numbers quoting Steve Sounders and as with any general number it is oversimplification. The number applies to the cases when backend is well optimized already. If you have HTML generated in 100ms it is quite likely you've got to invest in Front End optimization first. However if you have backend performing very badly - think 30 seconds to load the page, or even time out all together the distribution is going to be completely broken. The "right" approach is of course to start from the top and go to the bottom - if HTML is leading contributer to client response time you optimize it, else focus on other things. Dalin,

The rest is things like transfering images, CSS, and JavaScript. If you haven't yet, get YSlow and Google Page Speed and analyze your front-end performance.
