YUI Theater — Steve Souders: “High Performance Web Sites: 14 Rules For Faster Pages”

September 4, 2007 at 7:36 am by Eric Miraglia | In YUI Theater |

Steve Souders is Yahoo’s chief guru in the art and science of web performance and the author of the YSlow plugin for Firebug; he is the author of High Performance Web Sites, a forthcoming title from O’Reilly (bonus points if you can guess which animal O’Reilly’s editors chose for the cover of this one without looking at the picture to the right…). For the past three years, Steve has led a team investigating the root causes of poor page performance and applying the lessons learned to Yahoo!’s high-traffic, media-rich properties.

Over the past year, Steve has worked with Tenni Theurer (author of a four-part YUIBlog series on performance: part one | part two | part three | part four) and their Exceptional Performance team to hone the message. Last week, Steve reprised at Yahoo his recent OSCON talk which is derived from the past three years of research.

The details of this research are documented in Tenni’s articles (linked above) and in the Exceptional Performance section of the Yahoo! Developer Network website, so I won’t reiterate those here. Many thanks to Steve for his continuing advocacy on this subject and for allowing us to sharing his talk on YUI Theater.

I saw a lot of what you covered on the YSlow pages already but still a great presentation, Steve…thanks.

I’ll be putting in my order for your book from Amazon too when I decide on which LCD TV to buy :)

Anyone know what the software he used to generate the http request graphs?

I like IBM Page Detailer for the HTTP request graphs.

Steve -

I enjoyed this informative video. Two items concerning JS/CSS files seem to be needed as a web developer.

1.) EASY: ability to combine multiple JS or CSS files into 2 files (one for JS and one for CSS) for a given web page. I’ve already created it in CFMX.

2.) HARD: ability to scan all JavaScript functions and remove those function(s) not used (ie., user events, onload/onunload, css expressions) for a given web page. This would make the JavaScript as small as possible since, it would remove unused JavaScript for a given web page. If your team could create a server-side solution, this would help others. This would remove the ‘fatness’ from various frameworks.
