<p>Make sure Transmission's <ahref="portforward.html">port is forwarded</a>. You can check this in Preferences >> Network. Also make sure your upload is capped at an appropriate level.
<p>Some Internet Service Providers (ISPs) block traffic on well known peer to peer ports. If this applies to your ISP, try changing the port Transmission uses.
Some ISPs also throttle all peer to peer (esp BitTorrent) traffic, which can slow or even stop your transfers. Protocol encryption is not a feature at the moment, however is slated for a future release.
<p>Ultimately, the speed you get depends on the quality of the peers you are downloading from. If they have dial up connections, you are only going to be able to download at dial up speeds.
Furthermore, if there are few seeds and many peers, more people will be fighting for the same scarce pieces which will slow things down.
Best results are achieved when the torrent has more seeds than peers.
<h1>Why isn't my torrent downloading at all? </h1>
</div>
<p>Normally this is because the tracker is down, and thus Transmission is unable to interact with other peers. DHT (trackerless torrents) is not a feature at the moment, however is slated for a future release.
<p>If there are no seeders in the swarm, and all the other peers have sent you what they have, you (and everyone else) will not be able to complete the download, and your speed will drop to zero.
<p>Torrents take a while to get going and so may not download much (if at all) initially. Most torrents are downloading at some rate after 15 or so minutes.
<p>The fine, dark blue line on top of the bar shows the global progression, while the green line following it shows how much of the remaining download is actually available.<br>
<p>Peers are people you are connected to. If they have the whole file and are only uploading, they are referred to as a 'seeder'. If they only have part of the torrent, and are downloading and uploading, they are referred to as a 'leecher'.

<h1>What is the ratio shown during seeding? </h1>
</div>
<p>This shows your upload/download ratio - 1.00 means you have uploaded as much as you have downloaded, 2.00 means you have uploaded twice the amount you have downloaded, etc.

<h1>Transmission crashed, what should I do? </h1>
</div>
<p>Post the crash log on the <ahref="http://transmission.m0k.org/forum/viewforum.php?f=2">support forums</a> so that the issue can be fixed as quickly as possible. Crash logs are held in ~/Library/Logs/CrashReporter/
<p>'Nightlies' are releases on the bleeding edge of development. They normally contain new features and bugfixes, but are not officially supported (although you are more than welcome to discuss them on the Transmission forums). You can try one out <ahref="http://www.chucker.rasdi.net/opensource/transmission/">here</a>.
