For me Google Maps is slower than OpenStreetMap anywhere in the world, cache or no cache. Might have something to do with not using Chrome, where Google makes their websites work the best of course.
What do you mean by "the lack of precise zooming is super annoying"? In my experience, zooming in Bing Maps and OpenStreetMap are very fast, and only in Google Maps you're waiting ten seconds for the region to load and browser to respond before you can zoom further.
