@Anarki: I’m sorry to burst your bubble my friend but you are wrong. As kluelos told you already, the tracker does return to your client both the number of peers and seeds. Should you have heeded his advice and read the BitTorrent protocol specifications, specifically the Tracker Response section, you would have learned that by yourself.
Furthermore The Pirate Bay tracker is not “not working properly all the time theese days”. It doesn’t run at all, anymore. Period.
That’s since last November. They rely now solely on DHT and PEX for tracking the torrents they index.
This announcement was for a couple of weeks on their homepage, in November, and can still be found in the blog section of the site under the name of Worlds most resiliant tracking.
This is what accounts for the error message in the Trackers tab, since, obviously, this torrent was made before the tracker server was closed.
@lyckos: I’m not going to argue if you have a problem or not. I’m just going to suggest a few things to consider.
In your first two pics, indeed, there is a big difference between the number of seeds returned by your client and your sister’s.
I’m going to assume that both pics were taken after a fairly long amount of time, after that specific torrent was started in both of them (because if your torrent had been shortly started, then the whole comparison is irrelevant).
Still, that difference can be accounted by PEX and DHT. If your sister’s client connected different DHT nodes and peers than yours, it may have gotten from those, the extra seeds you were lacking by connecting to other peers which didn’t know about those seeds yet (the pool of peers was pretty big; over 1000).
Furthermore in your second set of pics, you can see that both your client and your sister’s client have the same number of detected peers (about 390) and only one seed. What’s more, even if she was connected to that single seed reported and you were not, your downloading speed was greater than hers.
Which thing obviates another fact related to the one I’ve presented above: that is, peers you connect at any certain point can have very different connection parameters and very often, in a normal healthy torrent, you get most of your downloaded pieces from other peers, not necessarily from seeds.
Sure thing, seeds are more appetizing to a client, since you’re less prone to get chocked, because they don’t expect anything from you in the “tit-for-tat” scheme.
But as long as you have peers with healthy connections, a decent upload speed per torrent, and the number of aggregate copies inside the swarm is reasonably high, you can finish a download, at very good speeds, without ever connecting to a seed.
Now, I’m not sure for how long has this little experiment of observation has been going, but you may want to carry it on a little longer, using identical torrent as until now, and focusing especially on the average downloading speeds both clients display, instead the number or seeds .
Provided you and your sister have identical Internet connections speeds, if you constantly (that is, in a matter of several hours on several days) get speeds much lower than the other client, then and only then you can really start thinking you have a problem.
Other than that, differences in displayed speeds are to be expected, since BitTorrent swarms are very dynamical network groups and your downloading speed at any given moment, highly depends on the individual peers to which you are connected at that particular time.
