I think Primal's image hosting service is massively capped on the number of simultaneous connections. Images on fresh posts (< 2mins) take forever to load because so many people are downloading at the same time. During that time, even if you open the link on the browser, it takes minutes for a 3MB image to load. If you let it pass a few mins, it comes back to normal speeds.

Nostr.build doesnt seem to have that problem.

iris.to is extremely fast too

Yes primal images always lag for me a lot

I've also noticed that Primal (at least used to) scrape images from outside hosting. The note will point to another host but their clients replace the media URL with their own host with the scraped media. Why do (did) they do this?

Is this why link previews never work on Primal? I didn't think I've ever seen a post with a working link, and I just can't use Primal because if it. Also, my DMs are seriously jacked on Primal.

always wonderd why it sucked so much

Thanks for reporting this nostr:npub1gcxzte5zlkncx26j68ez60fzkvtkm9e0vrwdcvsjakxf9mu9qewqlfnj5z. Strange, we were not able to reproduce this. Everything from our media server loads quickly for us from all nostr clients we tried. I believe you and others who reported this, that there's an issue, just can't repro it. Btw, we are not rate limiting anything on the media server and we are not hitting the ceiling in terms of bandwidth.

Last night we made a change in the way we work with our CDN, based on our feedback. This might fix the issue you reported. Please let us know if it works better now.

Nice! I will keep an eye on it.

It seems to always happen when a new post with 2 or more ~3mb pictures are present and lots of people are on Nostr at that time.

I don't know if this is a server side or a CDN thing, but it has been quite a reliable "issue" from Boston.
