Since caffeine my entire site updates at once, frequently

Twice within the past 2 weeks I've made sitewide changes and twice Google has updated their search index to reflect the change across almost all(98%) pages at once.

The site has roughly 5000 pages and the changes were to site title (removed .com from url) and site footer credit. I don't see Googlebot having visited every page in that time but it does have adsense sitewide in the sidebar so I imagine Google is retrieving some data (like titles) when data is collected from non googlebot crawls?

No matter - the speed is impressive and welcome.

I agree with you, it is impressive. Even though I criticize Google for many things, I am still blown away by what they've achieved and the scale they've achieved it on.

Yes, the Adsense crawls do share their data with the organic ranking process. Google has been using this "common cache" approach for a while now to save bandwidth.
