I was wondering why my speed was only about 250KB/s and I think this is why: there simply aren’t many high speed nodes in the network!

If you have a VPS sitting around, just spinning, do consider contributing.

With a simple docker-compose

version: "3.5"
services:
    i2p:
        image: geti2p/i2p
        container_name: i2p
        restart: always
        volumes:
            - ./i2pconfig:/i2p/.i2p
        network_mode: host

you can have i2p running in no time. Or follow the official installation instructions

Simply SSH with a local port forwarding to the router console ssh -L 7657:127.0.1.1:7657 $yourHost and open http://localhost:7657/

You can then configure your instance to share bandwidth.
