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.

One way to use the scripts would allocate them at the end of the page and thus the final code to be read by browsers and even though there is some delay in loading of the page content has already been shown. Some examples: Otimização de sites, Desentupidora, Relogio de Ponto and Acompanhantes

That is true, scripts slows down the page that you are accessing. This has happen to the Free Essay Library site where I get my free essays. I emailed them about the problem and they reponded by fixing the problem.

You are right! And also be careful because there are scripts that are also spywares. I once use scripts in my site home improvement and it makes my very slow to access. I remove the scripts and use wordpress.

Big thinking is where all the great leaders pull their energy, I just read Donald Trump's 2007 book. Stop by and learn about breast pills without the surgery.

what is bad with the javascipt is you have to install java foryou to run it and some java needs more space in your harddisk which makes your system run slow sika deer hunting | whitetail deer hunting
