I have been working to optimize my Page Speed score, and I found that loading a Google Map appears to give a 5 point or so penalty. It complains about a number of things, but the one that causes a yellow dot is the lack of a cache validator in most of the loaded resources.
In order to rule out anything I might have done, I ran Page Speed against the simplest possible map - the Hello World from the Google Maps documentation. Sure enough, it gets the same warning I get on my site. Run Page Speed against this to see the warnings.

Can these warnings be fixed? Or, in general, is it possible for any page with a Google Map to get higher than a 95 Page Speed score?
