I still quote his numbers all the time. This year Tim is going to talk about why and how Shopzilla took their eye off the performance ball, and what it cost them. I’m really looking forward to this one.

]]> Comment on How does Google measure site speed? by Tim http://timmorrow.org/how-does-google-measure-site-speed/comment-page-1/#comment-46 Tim Fri, 18 Jun 2010 21:39:18 +0000 http://timmorrow.org/?p=54#comment-46 Thanks for the comments. Although, you might be surprised at how quickly pages can be served with enough optimization. I can't comment on GWT itself. Here's an example of a page containing a CSS file, some images: <img src="http://timmorrow.org/wp-content/uploads/2010/06/lps-waterfall-e1276897296875.png" alt="Page performance waterfall graph" /> The full page load is 1.2 seconds; this was measured from a fairly typical DSL connection. All the images are served of a CDN. And I think there are even some optimizations possible here - like reducing the time it takes to emit the first bytes of the HTML to allow the browser to begin downloading the CSS and images sooner.

It states a website should load under 1,5 seconds. Yeah, good luck with that! Even a static HTML without any JS or else will not go much faster than 1,5 seconds.
