Description:
Scripts are the most painful resource to load in your page - they slow down the page more than images, stylesheets, even Flash. Why? Because when browsers start downloading a script, they stop rendering the page and downloading other resources. Even newer browsers that tout parallel script loading (IE8, Firefox 3.5, Chrome 2, Safari 4) still block rendering and downloads when loading scripts. In this talk, I'll present several techniques for avoiding these problems including splitting the initial payload, loading scripts without blocking, and coupling asynchronous scripts. This talk is only relevant for web sites that use JavaScript and want to be fast and have happy users.

Great material, lots of good information, but could save 3% in overall presentation download time, by removing "like", ", right?" and "So," from the beginning, middle and end of every sentence. domain.language.southern_california=false

Great presentation, best so-far at jQueryCon. Book-shilling is OK as far as it goes. I got a lot from following the slides downloaded from Steve's website.
Shame this session wasn't longer.

Definitely enjoyable talk. Good mix of entertaining, challenging, and inspiring (like his getting all excited about SpriteMe). Great job handling some of the questions and constructive criticism of his app. Awesome information on YSlow and PageSpeed. Will be very helpful to me.

Great job! I really hate script to my page. Downloading of my page is really slow and it is not good to the user specially for ecommerce website or any marketing site. You need to build a regular user of your page but if your page is hard to display why your customer stay too long to wait. essay topics | social essays
