Optimized is 20MB to 200KB. Dude's profiles load in 5 seconds, Girl's profiles aren't done loading after several minutes, or with refresh. Use netlimiter to slow yourself to 100KB then load some profiles, you'll see, not optimized.

Everyone uses different hosts, NB is not the only one. We have a special pfp.nostr.build endpoint that serves only optimized shit. So, in short, decentralized and disorganized is the theme here 😂
