I'm sorry, but measuring broadband performance on boxes using p2p is probably the most wrongest way you can go about it.

Saying you get 100k on box x, and 50k on box y, is bollox, as it all depends on how much other peers are uploading, how hard the seeds are getting hammered, what position you're in in peers queues, time of day, etc etc...

If you're uploading at 15k, and downloading at 100k, then you do realise that every packet that is recieved using TCP, it has to send an acknowledgement packet, to say it recieved it ok? Typically on 100k down, you're looking at about 10k up in acks alone, add on your 15k upload, and all the bandwidth for keeping 100's of connections to peers open, and you've pretty much max'd out your upload. Thats why it takes ages to download web pages.
