For both seeders and leachers, there are two numbers (the second is in parentheses). What is the significance of the two separate numbers?

First one denotes how many peers you're connected to, second one shows how many peers there are in the swarm that you aren't connected to.

Now I'm curious about the peers in the swarm that you aren't connected to. I suppose that you might not be connected to them because your IP address has been filtered out, etc. But I expect most would not be connected because their computer is turned off. Or, at least, their bittorrent client is not running. Am I right? Any other reasons?

Is a peer removed from a swarm if the torrent is deleted from the client? How about if they simply delete the data file, but don't ever delete it from the client? Is there a process to remove the peer from the swarm if they simply don't ever access bittorrents any more?

Do torrents last forever? (Maybe we can start an urban legend that 20% of the bittorrent clients today are trying to connect to the original ENIAC!)


Sorry for all the questions - I really don't have time to dig into the technical specs... (Ok, I'm also too lazy!)

There's many reasons why you're not connected to them. I.e. they don't have interesting pieces; you've reached maximum number of connections; there are better peers.

Then they don't show up in swarm.

No

Many more.

Peer is removed when it sends appropriate event to the tracker (e.g. „stopped”). Or dies (tracker can't get response from it).

No. They can be removed from tracker. There can be 0 of full copies availible. The tracker could stop working.
