My link for the testing machine running the BT client is 1 Gbit/s. So it should not be the bottleneck.
1 GBit/sec is not the universal answer. I guess your international routing is not well-equipped.
I don't know how well equipped things are here, I am not in charge of routing. Anyway I would expect it to be quite standard, they run a 10 Gbit backbone at the university campus, and they are hosting the national internet exchange, where they then also have a number of international lines. Are you talking about international connection bandwidth?
You should not judge other servers or protocols if you can't manage to download _anything_ from _some_ server located in the same country or region with the speed you want.
Well, I am not trying to blame anybody. I am just puzzled over some things. And then I am asking people on this list as I think they are quite knowledgeable in what is going on.
I do get fine speeds from other servers in Denmark, say 200 - 300 Mbit/s.
I am still puzzled.

This is geant2 http://www.geant2.net/server/show/nav.941 - and a direct international link Copenhagen - Frankfurt of 10 gigabit is used. How can this be a bottleneck?
