My router was showing 256k, and uploads achieve that. The phone line to the house was one of the first two to be installed in the street (the other is next door) and the best connection speed I ever see is just under 3Mb.
This may take a little while....
I get 6Mb/s downloads quite regularly (typically 5.7Mb/s), but haven't seen better than 380kb/s upload, so on that basis you're upload to download ratio is better than mine!
