+## Tuning Dragonfly DB
+If you are attempting to tune Dragonfly DB for performance, consider `NAT` performance costs associated with containerization.  
+> ## Performance Tuning
+> ---
+> In `docker-compose`, there is a meaningful difference between an `overlay` network(which relies on docker `NAT` traversal on every request) and using the `host` network(see [`docker-compose.yml`](https://github.com/dragonflydb/dragonfly/blob/main/contrib/docker/docker-compose.yml)).
