the US is further away meaning higher latency.

higher latency means the same size rwin gives you lower speeds, their may be also other factors involved with the longer distance.

first I would tweak your connection by raising the rwin etc. need to reboot to apply changes.

then if no improvement or improvement not good enough try multithreading your downloads. Many here only get 10meg when doing silmultaneous downloads on their nntp clients.

given that downloading from america is not the ideal way of high speed downloading and ntl's .us peering is poor I would try a eu news provider.
