Thanks to a comment by @LargeHardonCollider@lemmy.world , I checked and saw that ‘Federation debugging’ mode was enabled. I had enabled that when the server just started (less than 3 weeks ago) and I had an issue with federation.
I thought I had switched that off again, but apparently not. This mode causes the federation to be done in the foreground, so your ‘Post’ or ‘Comment’ action will wait for that to finish…
This solves the most annoying issue, and makes the site way more useable. There are many other issues, but we’ll get there.
Nice! Do you notice any change in other metrics? CPU/Memory usage?
Off-topic: @ruud@lemmy.world, what is the best way to report someone to the instance admin, in order to get them banned from the instance?
It seems to use a bit less CPU.
You should just report the post/comment they made. The community mods as well as the admins will receive the report. If it’s really bad, you could e-mail info@lemmy.world
