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!

The empty cache makes sense. Firefox is defaulting to automatically clearing the cache on shutdown........... I check my "usual" sites everyday so the 1st visit is refreshing the cache, the rest of the browse for the site uses the cache...........
