Is there an upper limit to the number of subscribers to a pubsub channel? Is there a number where it starts to break down?
I’m in the process of building a network that I anticipate to grow to large numbers of IPFS nodes, and they all coordinate using pubsub. I’m trying to anticipate if there is some upper number where I should consider sharding the channel.
If people reading this have experience running sub-networks using pubsub, please share the maximum number of nodes you’ve run, and if you saw any issues with communication over pubsub.
