I've noticed that slowness quite a few times; most recently with my last post, "Re^3: Listing out the characters included in a character class [v5.38]", which I just posted some minutes ago. It's quite long and took a few previews to fix minor typos: these all occurred in a resonable time. When I hit create, I had to wait minutes for anything to happen. That sort of thing has occurred on quite a few occasions over the last week or so.

Also, when going back just now to get the node_id for linking, I see the timestamp is completely wrong. It shows "Oct 28, 2023 at 15:42 AEDT". The timezone, AEDT, is correct; but it's just after 7am on 29th Oct here. I don't know if that's related or helps with troubleshooting.
