Have been using it for quite some time now and honestly I have found almost everything I searched for and once you set the router bandwidth properly, I was capable of downloading and seeding with 2MB/s. Satisfied my needs and gotta say not worrying about Letters coming to you is very calming
How is it compared to private trackers?
I don’t know of any private trackers on i2p and have just used Postman mainly (the other trackers have very limited content). Postman is OK but not nearly as good as regular private trackers. If what you want are blockbuster films and the latest TV, you’ll be fine. Anything particularly nerdy you will probably find too.
There really should be more private trackers on I2P. Once you get over the slower speeds, there are a lot of benefits, like not really needing to port forward to be connectable (but you should to support the I2P network).
Ive been torrenting on I2P with qBittorrent for a lil while now, its not as fast as the clearnet, the fastest speed down ive ever got so far is 1.7MB/s, and this was on a torrent with loads of seeders. Its possible to increase your tunnel quantity and lower the amount of hops each tunnel has for better performance, but you will have less anonymity with less tunnel length.
But so far its been nice, there is no need to think about NAT/Firewall, as all peers can communicate with each other, but it doesnt have as much content as the clearnet, so I try to cross-seed what I can. But when im torrenting, I try to go I2P-first, and then fallback on the clearnet if I couldnt find what I was looking for.
If have open port than I2P is faster (still not fast, but much better) because you actively contribute to the network.
