nostr:npub1x3azxuysp5vmfer4vgs4jn5tmfcx4ew8sh0qnev7gczljxsr7jwqa3g4el does it really use that much bandwidth just pushing text around? most bandwidth usage is media but nostr doesnt serve that.
Discussion
Most bandwidth is from downloading notes from numbers of relays. So say each 10 relays are being requested to return last 100 events to a client.
That itself including duplicate event is already totalling 100*10 = 1000 events being received by client. Compression still proved ineffective on handling this kind of buffers as some nostr clients still tend to be intensive when requesting events to nostr relays.
If nostr client still keeps requesting for another 100 events to these 10 relays, You already know what happen next.
