I have noticed this too in recent versions. I don't remember the exact point it changed unfortunately, but it used to be almost instant and I am now seeing very long load times after clicking "view in my instance". I thought it was just something with my home instance.

This isn't a new thing. Essentially every "object" has an id and there is a translation API built into Lemmy that allows you to look up "an object" associated with an id on the current instance. The app uses this API to let you see a post from any instance. The logic has been the same for a very long time.

I see the same thing loading messages, etc. I'd assumed the instance was slow, but maybe not.
