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.
The Exceptional Performance team has identified a number of best practices for making web pages fast. The list includes 34 best practices divided into 7 categories.
YSlow analyzes web pages and tells you why they're slow based on the best practices for high performance web sites. YSlow is a Firefox add-on integrated with the popular Firebug web development tool. This tool has helped improve the performance on over 50 Yahoo! properties by 25-50%. We're pleased to be able to share this with the development community so that others can join us in accelerating the user experience on the web!
Research conducted by the Exceptional Performance team is documented in the following Yahoo! User Interface Blog articles.
YSlow and performance topcis are discussed on the Exceptional Performance Group. Use this group if you have questions, issues, or need technical support.
You can also send feedback and report YSlow bugs and feature requests using the feedback form.
Along with the general web developments videos, you can also enjoy several performance-related videos now available on YUI Theater.
