Let me at first make some facts clear:
Your ratio is only calculated by your upload traffic divided by your download traffic. Seed bonus points (SBP) are only used to add to your upload traffic, in your case 100 SBP = 1.0 GB = 100 / 2.140 GB x 1 GB = ~0,04 % increase. (all values are rounded).
You get SBB for the time seeding 1 point for two hours seeding time. The number of torrents is irrelevant, only the time seeding counts. I see members here which seed >200 torrents at the same time: nonsense, their client uses probably more time to manage the seeding torrents than to look out for more downloading members for a few torrents.
… the upload speed is ridiculous and most of the time nothing happens ,-...
For the upload speed see MrMada's answer, btw: if you look at his posting you can see easily he is a GlobalModerator (and another btw: has much more knowledge about IN-technology than I have and probably will ever get)
meanwhile I seed on other torrent site at 600 kb/s
depending on your speed and the swarm-size that can easily be explained.
(and I've tried stopping these to see if things got better on GT.ru, not the case), on GT.ru it usually remains below 1Kb/s .
Well - to dig deeper we need a IN-speed diagnostic from a widely accepted source like www.speedtest.net and mail us your results. The effective upload speed is influenced by numerous things: most important: connectivity of the clients, the available ressourses for uploading, # of leeching clients in the swarm,#of seeding clients in the swarm and may many more.
I was previuously seeding huindreds of torrents
See my remark about seeding many torrents!
What we didn't discuss up to now is the question of ports; open or closed, firewalls and so on. All things GT.ru has no influence. Our tracker has the only task to to convey IP-addresses of seeding/leeching clients - the transfer is the client's duty!
see also my message https://forum.gaytorrent.ru/index.php?topic=30593.msg145307;topicseen#msg145307 in this very forum about port forwarding and telated stuff
What could have been changed in the last few months to make it this way? …
In case you did read and understand my last paragraph you can answer this question yourself:
NOTHING
and your problems are the connections between your client and other clients. That's the reason BitTorrent is called a Peer to Peer network meaning: it is not centrally organised.
Can a mod/admin help ?
At least MrMazda and I tried 😉
