Please note that most of the bw in Asia is to other parts of Asia. There is lots of peering and lots of fibre. Trying to get to the US, on the other hand, and you have a few, very expensive (comparatively) cables. This is why you find cloud companies in korea doing live disk replication into japan. The fibre in the region is just so cheap that it just doesn't matter anymore.

You would probably notice that if you were using local (or even localish) sites, that there would be a dramatic improvement.
