ABSTRACT

Yahoo!'s Exceptional Performance Team has identified 14 best practices for making web pages faster. These best practices have proven to reduce response times of Yahoo! properties by 25-50%. They focus on the front-end, for example, why it's bad to use "@import" for including stylesheets and why ETags disable browser caching. In this talk I'll go in-depth on these best practices and the research behind them. I'll also demonstrate YSlow and do some live performance analysis of popular web sites.
