Hi Martin, my ping alone is 170ms, so I won't explore this argument further. Also I think the comparison between loading a map and the map API is not correct - I am comparing the time needed to show my application with and without the maps API (always taking the naive, blocking approach) and at least for recurring visitors, the difference in user experience is notable.
Are you sure 3 and 4 are loaded simultaneously with the AjaxLoader? As far as my understanding of the bootstrap process goes, 4 is launched by the application itself, which cannot be sooner than 3 is loaded.
