Hello People,

quick question (confirmation). I've got a server with 32 GB ram and 4vcpcu for one elk node (v7.11.1).  
If I set this in docker-compose (v.2.4):

```auto
 mem_limit: 24G 
    mem_reservation: 4G
    cpus: 4

```

And set JVM heap:

```auto
-Xms16g
-Xmx16g

```

Would it be correct ?
