In this project, a two factor full factorial design on workloads and BT clients was proposed to test which effect is significant for BT downloading. The first part presents the background knowledge of Peer-to-peer(P2P) and BT and the introduction of several popular BT clients. Next, a two factor full factorial design was shown. The result indicated that "torrent" was the primary significant factor, while "BT client" was the secondary factor. Also, there was another experiment on out-of-date torrents to test which BT client was successful to download them with few seeder and peers. The result indicated the BT client "µTorrent" was strongest in this task. Keywords: Measurement Study, Peer-to-peer, Experimental Design, BitTorrent, BitTorrent Client, Torrent 1.
