Does the Peer-to-Peer download speed decrease after a few days?
It is true that the download speed decreases after the first days of hosting. But minimum speed is about 70KB/s (of course, it depends on your Internet connection), which is already sufficient in general. Thanks to the Peer-to-Peer effect, this speed can increase significantly if many users take part in the transfer, which occurs if the same file is sent to several people or if they forward the file to many friends. To take a theoretical example: if you are 10 to receive the same file, you will obtain potentially 700KB/s!
