At TorrentFreak we have written quite a few speed guides, but we are not as knowledgeable as the people who work with BitTorrent clients daily. A few weeks ago we asked Olivier Chalouhi, developer and CTO of Vuze (formerly known as Azureus) to share some of his BitTorrent speed tips with us.
Today we continue our mission to help people get the most out of BitTorrent, by asking uTorrent developer Greg Hazel to give us his recommendations on how to optimize BitTorrent download speeds. Here are his three suggestions.
Cap the upload speed
Limiting your upload speed is by far the most important suggestion, and was also mention by Olivier Chalouhi in our previous BitTorrent speed guides. The rationale behind it is simple. Your connection is a tube (sort of), if you max out the upload capacity, the tube gets clogged.
Choose the correct maximum number of connections
Too much connections can actually slow down your torrents, instead of increasing the download speed. The uTorrent speed guide (Options > Speed Guide in uTorrent) automatically recommends the ideal settings. For users with a maximum upload speed of 256 kbit/sec, uTorrent suggests a maximum of 35 connections per torrent, and 60 in total.
Run as few torrents as possible
Less is more, sometimes at least. Running fewer torrents will guarantee that your connection can handle all the connections and requests properly. Since BitTorrent rewards people for uploading, the less torrents you run, the faster they will download. Again, the uTorrent speed guide will suggest the optimal settings, which is a maximum of 2 torrents for users with a maximum upload speed of 256 kbit/sec.
These three settings are the most important according to Greg, and configuring them correctly in your BitTorrent client, is the key to faster downloads.
