Yes I'm speaking about Damus, Primal, Nostrudel, Snort, etc. The classical web client without any integrations of livestreams or something else. I think (but I may be wrong) the "note system" is more heavy regarding file downloads during a normal feed use. It already was a subject few months ago with Amethyst that was consuming a lot of network bandwidth on phone but it seems it's not an application issue, it's more a Nostr by-design behavior. I will do the test with kasm and I should be able to compare both use.
