I was playing with Nostr again and this time I installed strfry to my local computer despite having my own relay on VPS. Then I asked ChatGPT to give me this management script (https://rootservers.eu/manage-relays.py.txt ) that opens streaming to configured list of relays and starts a local relay. When I connect nostrudel just to my local relay that gets all the messages from everywhere, it works super fast. So, this is how you are supposed to use this. I think I understand now.
