Since i installed the w§ Total Cache i really have the feeling that the blog is loading faster. But if i take a look in the Google Webmaster Tools they say the page is going slower.

(Installation was at the beginning of may)
So what's reason? After thinking about that a while i had the idea that the site for visitors is really faster but not for bots. because they are excludes in the standard configuration.
But Google use the loading time (calculated with their bots) as one critea for the placement in the SERPS.
So whats the right way? Cache all pages also for the bots? What's the disadvantage when caching pages for bots?
