nostr:npub1y7t7qfvwj5c9t00yweayr669a407reszhyv7y957pdgwd6scfs3qj76drl cloudflare helps, however they still have like a hundred data centers that each have to make their own requests. if you post a 30mb video you will saturate your 30mbps upload for a while as u have to upload gigabytes at once
with my setup nginx would only make one request for each file, cache it and then serve it to everyone. single 30mb file would take 8 seconds to upload
