I haven't looked at the article yet and only superficially poked around with I2P, but I think the idea is that user adoption is the key to better speeds and reliability given the P2P nature. That said, I found it to be daunting as well just getting into it.

Privacy and security in general are like that for me because a lot of the pitfalls come with how you use the tech and not just the structures they provide.

Yep, this is the same thing that happened last time. I got my Monero wallet up and running over an I2P node again, and I can barely get 100 Kb/s. It will jump to a max of 1Mb/s rarely and then drop right back down again. On tor i get more like 400Kb/s average instead of barely 100.

~~That is correct. i2p is designed such that peers are expected (required?) to share some bandwidth to be on the network.~~

Of course, that bandwidth stays in-network (unlike Tor which supports “exit nodes”) so it is less risky to share.

Edit: I’m totally wrong, oops

It's not required but default on. there's a setting for it, but also if it detects from your IP that you are in a risky country, it'll not enable the functionality to bridge other traffic

I think 300KB/s is around the max possible in the current implementation:

Encryption, latency, and how a tunnel is built makes it quite expensive in CPU time to build a tunnel. This is why a destination is only allowed to have a maximum of 6 IN and 6 OUT tunnels to transport data. With a max of 50 kb/sec per tunnel, a destination could use roughly 300 kb/sec traffic combined ( in reality it could be more if shorter tunnels are used with low or no anonymity available). Used tunnels are discarded every 10 minutes and new ones are built. This change of tunnels, and sometimes clients that shutdown or lose their connection to the network will sometimes break tunnels and connections. An example of this can be seen on the IRC2P Network in loss of connection (ping timeout) or on when using eepget.

I've seen speeds in the Mb/s range, although rarely.
