Google Maps. Small optimization
Last December, I wrote a post (http://olegi.habrahabr.ru/blog/46641/) about some weirdness with the service.
Gray backing, brakes, etc. Psot successfully zaminusovali :-). Today I decided to reveal the reason.
It turns out, Google decided to optimize the service. First, the "gray" light map is loaded, and then on top it is already full color.
The effect is noticed thanks to the slowing-down ISP "Akado" and no less slowing down IE6.
UPDATE : for those who sympathize with traffic.
1) I noticed this “optimization” only on the desktop version of the service, it is not on mobile phones.
2) For mobiles in general, other tiles use. On iPhone 2 version - 64x64, 128x128 (for the latest firmware) pixels. But with a fresh version of Google Maps for Mobile (Windows Mobile) - for some reason, there are no house numbers on the tile (I am shocked !!! 111)
