Hello, i found around 80 trackers that shows "Working" status when i add them into the torrent.
80 seems to be alot, but this torrent has usually has one or no seeder so i do not want to miss any seeder by lowering number of trackers.
I do not know what to do to balance between availability (as much seeders as possible) and not eating too much connections limit (i read many trackers can meen exhausting of connections). I have not found how often qbittorent reannounce to Working/Not working trackers.
My limits:
1.Global maximum number of connections: 500
2.Maximum number of connections per torrent: 26
3.Global maximum number of upload slots: 21
4.Maximum number of upload slots per torrent: 5
5.Max half open connections: 6
Usually 1-5 Active torrents with 1-8 peers. Total 250 torrents in seeding/DLing state.
When there are 2 Active torrents, 2 peers, i see "Total peer connections: 17" in View/Statistics. DHT enabled, qbittorent Windows.
How to calculate right number of trackers per torrent?

Re: How to calculate right number of trackers per torrent?
qBT retries a tracker on each started (but not queued) torrent typically every 30 minutes.
Trackers are dying off from overloads, (they have connection limits too as well as bandwidth costs) so adding more trackers that weren't inside the original .torrent file means you're probably just contributing to the death of them without increasing the torrent's availability any.
If the torrents are public ones then DHT, LPD, and especially PEX help find other peers and seeds on torrents...this means lots of extra trackers are pointless.
Your global max. number of upload slots is your main limiting factor (on your end) in how many torrents you can have active at once...
since a seeding torrent isn't really seeding unless you're uploading to a peer on it.
That may be partially why you have 1-5 active torrents instead of possibly 2-10.
I take it your max usable upload speed in qBT is only about 100 KiloBYTES/second?
