@alex @e @mint @graf @sjw @lanodan They did and CPU usage went down a tonne. Only slight above normal.

See the settings I'm using. I think it had to do with the higher work_mem

100 connections was enough to keep plerona from crashing.

After about an hour or two it stopped bitching in the logs, CPU went away down, and it started chugging along.

I also ran a vacuum analyse on the database while it was running. Not sure if that played a part or not.
