Do you mean in the container under `db_shared_buffers: "4096MB"`? It says 25% of total memory (server has 64GB) so Ill try upping this to 10GB.

That’s the only performance related setting I can recall… are there any others we should be aware of or routinely checking/tweaking?

**Edit** : just looked and there’s also:

```plaintext
  ## can improve sorting performance, but adds memory usage per-connection
  #db_work_mem: "40MB"

```

Any threads that discuss this anywhere? (Or do you or anyone else have any thoughts?)
