Many seeders available, few connected
This is an old question, but so far I have not seen a satisfactory answer.
Why does uTorrent show dozens of seeders / lechers available, but only connect with just a few?
In the example below, uTorrent shows 11 seeders available, but only connects with 5. The same with peers, 39 available, but only connects with 6.
In this image we can see a detail of the connections:
In addition, my connection is optical fiber, high speed, I configured properly uTorrent not to limit the number of downloads, nor speed.
But after all, uTorrent insists on always connecting to fewer seeders/lechers.
Would anyone know how to improve this?

Because, as per the uTorrent forum, there's an optimum number of connections.
Doyen IT columnist Robert X. Cringely once reported he got best throughput with six torrents underway; more connections, less total speed, as per his experiments. (Wish I could find that blog post....)
2There is lot of uncertainty in the number in the parentheses as it is an estimate.
In the example, µTorrent most probably don't succeed to connect to the other 6 possible seeds.
The client tries and accept connections until it reaches one of the limits set in:
Preferences (Ctrl+P) > Bandwidth
- Global maximum number of connections
- Maximum number of connected peers per torrent
From µTorrent User Manual (Press F1) > Appendix A: The µTorrent Interface > Main Window > Torrent Jobs List:
- Peers displays the number of peers you are connected to, and the number of peers in the swarm within the parentheses. The number of peers in the swarm is an estimate based on the maximum number of peers found either between the amounts reported by any tracker, or the number of peers µTorrent has encountered within its peer cache. If the torrent job is stopped, and bt.scrape_stopped is enabled, µTorrent will show the maximum number of peers in the swarm as reported by the tracker scrapes.
- Seeds displays the number of seeds you are connected to, and the number of seeds in the swarm within the parentheses. The number of seeds in the swarm is an estimate based on the maximum number of seeds found either between the amounts reported by any tracker, or the number of seeds µTorrent has encountered within its peer cache. If the torrent job is stopped, and bt.scrape_stopped is enabled, µTorrent will show the maximum number of seeds in the swarm as reported by the tracker scrapes.
