On of the most interesting presentations at FOWA2007 so far was the performance tuning talk by the Chief Performance Yahoo! Steve Sounders. He revealed very suprising results regarding their approaches and experiences regarding tuning website performance.
The most core aspect of his talk was that 5% of all latency times are produced by the business logic and all other backend stuff of your application. The other 95% (which are the ones after loading the HTML-page in the browser) are about loading images, flash files, movies, css files, javascript files as well as the interpretation of the css and the javascript.
Furthermore he recommends rules for developers how to minimÃze these latency time where the user is waiting for the page beeing displayed.
The most important ones are:
Furthermore Yahoo introduced !Yslow as a Firebug/Firefox Plugin to analyze web traffic and return recommendations for performance tuning.
Finally check this video to get more glue on it.
I was very impressed by their results and we are definitely going to test this out for our clients applications and see, if we can there add some more speed for the users accessing the pages.
