Edit: This was a post about trying out a "5 Mbps Slingbox". I moved to a new internet provider (100 Mbps down / 5 Mbps up) & wanted to test my Slingbox speeds to different countries. I found out that the speeds are accurate for shorter distances. But get a lot slower as you get farther away.
I'm not completely sure why the speeds are poor, but Google finds lots of people claiming that many internet companies, including mine, use traffic shaping to reduce upload speeds. Apparently a lot of (most?) consumer plans won't sustain a long distance upload above 1 Mbps either because of slow backbone links or because their provider uses traffic shaping to throttle out of country connections.
Here are the speeds that I saw if you are curious
(Slingbox is in Canada)
4.6 Mbps USA
4.5 Mbps Canada
3.8 Mbps Switzerland
1.3 Mbps UK
0.9 Mbps Mexico
0.7 Mbps Belgium
0.6 Mbps Australia
0.6 Mbps Brazil
0.6 Mbps France
