I made this post before but it got removed due to the spam filter.
I ported my site to next.js with a prismatic headless backend. The files get statically generated but still, the images have a very long TTFB (4.2 sec). Last time I posted an attachment of the request the entire post got flagged as spam so I guess you just have to take my word for it.
The instance is " serene-colden-83caab" and there is no DNS so it’s all on the platform.
