Yahoo: 13 rules for making your web pages faster
As if that wasn’t enough, the team just released a Firefox add-on which integrates on top of Firebug, a web development tool. This add-on will analyze any web page to check for how they comply with the 13 rules. Once your page is analyzed, it will give you a letter grade, just like in school, on how your website fared against the various rules.
Yahoo has really compiled a great resource for web developers and I think everyone should take advantage of it. So, give the list a read, grab the Firefox add-on and see how you can help those page load times out!
