From http://tinyurl.com/dsq3c average packet size seems to be about 620 bytes.. which means that we may not achieve full 10Mbit speeds..

And that's presuming that we do no uploading at all!
Downloading files average packet will be as large as your MRU which is by default 1500 bytes.

If you've problems with that ratio blame Telewest's obsession with staying uncapped. They happily let people upload full pelt 24x7, their problem to be honest.
