Google has placed a great deal of emphasis on speed for the last year or two, offering numerous tools and resources aimed at speeding things up. In fact, Google has even attempted to speed up the search engine itself with Google Instant. 

In mid-June, Google commenced an initiative known as "Let’s make the web faster."  Late yesterday, the search giant performed a follow-through of sorts with the release of an experimental feature called "Site Performance."

Google has a post up talking about how the company uses data it collects from Google Toolbar users, specifically in relation to its enhanced features. These features are opt-in.

Google has begun an initiative to help webmasters all over the web make their sites faster, and in turn make the entire web faster for everybody. This would reflect Google Co-founder Larry Page’s vision of people being about to surf the web as quickly as if they were flipping through the pages of a magazine.

Google will make landing page load times a factor in computing the quality score, which could have an impact on minimum bid prices.
