I prefer bing, it’s better, smoother, faster more user friendly and that’s why people are switching to use bing maps instead of google maps.

GMaps: ~162ms = 98.8 kb/s
Bing: ~160ms = 100 kb/s
10 refreshes each

Note: Bing varied widely, much more so than Google. First result was 384 ms. second was 320 ms. third was 150 ms. most of the rest were 130-160 ms, but I had another >300 ms. GMaps tended to stay right around 150-160 ms.

Thanks for you help David. I have added a bit to the blog post telling readers how to load each test without using the browser cache.

United States
GMaps: 484ms = 33.06 kb/s
Bing: 558ms = 28.67 kb/s

NOTE: The browser cache must be cleared between tile fetches because MS is setting Etag and Last-Modified headers while Google does not. Consequently, my initial tests showed the transfer times for subsequent loads from the MS servers to be artificially low because the map tile was being loaded from the browser’s cache (after receiving a 304 response from the server).

If Firebug reports “1 request 16 KB (16 KB from cache) 42 ms” instead of “1 request 16 KB 488 ms”, you should not factor that time into your average speed.
