This paper presents an experimental study on the behavior of BitTorrent networks when selfish peers attempt to maintain high download rates without uploading. This paper modifies a BitTorrent client so that it acquires a larger than normal view of a BitTorrent swarms and connects to all peers in its view. The experimental results show that; the modified free-rider client can achieve better download rates than a compliant client in most common-case public torrents; when the percentage of the modified free-rider clients in PlanetLab-residing torrents with 300 leechers is less than 40%, free-riders on average outperform compliant clients; and as the number of free-riders increases, both free-riders and compliant clients incur substantial performance degradation.
