nostr:npub1nmr6w7qk0ta36vxysv77jv3d5rqghfc6d8sez8240rf3gja4vsmsd2yha8 forgot to mention there are diminishing returns after 20 connections. I think your chrome testing was capped around 30?
At the moment with the current state of nostr, just for outbox I agree that there are diminishing returns after about 20 or so relays, but in addition to the outbox relays, the app still needs to open more connections to find replies. Turns out chrome is fine, it was Brave Shields preventing more connections.
