Port forwarding makes it easier for others to connect to you, which therefore increases your speed. <div summary="To do this" id="taskbox"> <p>If your router supports NAT-PMP, UPnP, or you have Apple AirPort, Transmission can do this automatically; just tick the checkbox in Preferences -> Network. </div> </li> <li>Make sure you cap your upload speed, so that it isn't flooded. A good rule of thumb is about 60-70% of your maximum upload bandwidth. This can be adjusted in Preferences -> Bandwidth, or in real time using the Action menu. <div summary="To do this" id="taskbox"> <p>eg. If your upload connection is 256 Kilobits/sec, then you should cap it at 21 KB/sec ((<b>256</b> / 8) * 0.66 = <b>21</b>). </div> </li> <li><a href="gettingstarted.html#queue">Queue</a> your transfers. Transmission's queue preferences are located in Transfers -> Management. <p>Remember, your download speed is proportional to how fast you upload. If there are many transfers running, then each transfer will only receive a small proportion of your upload bandwidth, reducing their respective download speeds. To avoid spreading your upload too thinly, a good rule of thumb is to have at least 128 KBit/sec of upload bandwidth for every torrent you wish to run simultaneously. <div summary="To do this" id="taskbox"> <p>eg. If your upload bandwidth is 256 KBit/sec, then you should only have two (<b>256</b>/128 = <b>2</b>) downloading transfers in the queue. </div> </li> </ol> </div> </div> </body> </html>
