High Performance Web Sites and YSlow


Google Tech Talks November 13, 2007 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.

    I swear to god, microphones must be one of the hardest pieces of technology to use if even Google can’t seem to figure out how to get them working right!
