Is there any technical limit for scalability by lowest bandwidth rate limit or any curve x = number of nodes, y = minimal bandwidth limit?
What settings are optimal for huge amount of small middle relays?
Not that there's a technical bandwidth limit but it's probably not gonna be helpful for the network if you run a relay with less than 100KB/s bandwidth. For that it simply slows the network down. You can add as many relay as you want, as long as you configure the
If you have less than 100KB/s bandwidth, you may consider running a bridge relay. (there's no need to set
MyFamily for bridges)
