Well, that’s really sad to hear that Tribler does not work for you
Under the hood, Tribler uses LibTorrent library. You can try using another LibTorrent-based client, such as Deluge, and report back if it solves your problems. If it does, that’s good news for us, since we can probably fix it. If it does not, the problem is probably in LibTorrent itself.
Recently, it was discovered that LibTorrent has a bad problem with UDP-based connections with other clients. Deluge is affected too.
Also, there are two Tribler-specific issues:
- The first is about sharing magnet links for rare torrents.It was solved recently. The first release with the fix is 7.10
- The second one is much more tricky. When you seed anonymously, the torrent you seed is only available through an anonymous tunnel, which adds a lot of latency, which affects the upload speed negatively. This means that external downloaders will prefer other seeds, if available. Non-anonymous seeds are much faster. So, when you seed something anonymously, don’t expect to see good upload rates, unless you’re the only seeder out there. And then - see problem #1 above
In short: try Deluge, download the latest 7.10 experimental release, don’t use anonymous seeding unless absolutely necessary.
