Hi,

I'm downloading a file without much speed, and this confuses me:

Code: Select all

Seeders: 0 (900)

What does that mean exactly?

It's the scraped information provided by the tracker

Seeders: 0
means that there are 0 peers connected to you

Seeders: (900)
means that there are in total 900 peers in the swarm, wheither connected to you or not. (minus the banned peers by IP filter)


900 seeders in swarm and 0 peers connected to you looks like there's something wrong though.
Does this happen with one particular tracker or torrent?

Thank you for your answer. The numbers are now 1 (894) -- not much better. I'm not using the IP filter at all, so it's a bit strange.

I often see differences between these numbers, no matter what tracker or torrent. But this difference is much larger than normal.

For this particular torrent I also have Leechers 38 (454), and most of those 38 are at 97,9% of the file.

Well it looks like many seeders are firewalled (and that you have to wait on their announce to connect to you), but all 900 peer firewalled would be near impossible.

On very large swarms though (approx 100+ seeders and 100+ leechers), trackers commonly provide your client with only leecher peers in an announce reply. So i think that would be probably the case.
After a while you'll normally get connected to some(but still less) seeders when you upload at a decent level.

This should only happen in big swarms.

You could play with the number of allowed connections per torrent and see if that makes any changes. (but be carefull when your internet connection that isn't that high bandwidth(it can convert to smallband) and also, some cheap routers will fail under high connection load)

Yesterday another extreme example appeared: seeders 2 (2000), leechers 10 (3500). Those are approximate numbers. Speed up and down was quite low even after several hours, never above 10KB/s. I tried the same torrent with the simple native bittorrent client, and the speed was slightly better there. With Azureus the down speed quickly reached about 150KB/s.

And if you do a couple of manual announces ? Maybe this tracker uses a long interval, and doesn't give back much peers. Are you behind a firewall or router yourself ?

I haven't really tried that... I'll try when the problem next appears.

Maybe, but that implies that Azureus does "manual announce" itself.

Yes, I'm behind a NAT, so no incoming connections for me.

If your router supports UPnP I suggest you try the UPnP plugin, which will forward your ports, so you can get incoming connections.
