This Is Why Your Website Is Slow

I don't think so. In the Webmasters Tools you can see that Google has metrics for "Site performance" [1] and for "Time spent downloading a page (in milliseconds)".

Also, you can see that Google is running JS and loading flash by looking at the Image Preview that appears when you search.

So we're basically both right, but I was wrong in my initial assessment. Their crawler doesn't give them the page speed metrics, they get it from their toolbar data:

Page load time is the total time from the moment the user clicks on a link to your page until the time the entire page is loaded and displayed in a browser. It is collected directly from users who have installed the Google Toolbar and have enabled the optional PageRank feature.
