Using the Azureus client, I downloaded a popular 350MB torrent and seeded
it to a 1:1 share ratio at 20KB/s upload rate while connected with 200
peers. The resulting overhead? According to the statistics view:
5.6% download overhead
5.7% upload overhead
These numbers should be even lower when connected to fewer peers.
