     3  To get the best performance, you'll want to ensure that Docker is configured properly. These are the environments known to produce the best results:
     4  
     5  1. Linux 4.7 or newer with aufs or overlay2 module.
     6  2. Ubuntu 16.04 LTS or newer with aufs or overlay2 module.
     7  3. Docker 1.12 or newer to be available.
     8  
     9  It is important to reconfigure host's Docker with this filesystem module. Thus, in your Docker start scripts you must do as following:
    10  
    11  ```
    12  docker daemon [...] --storage-driver=overlay2
    13  ```
    14  
    15  In case you are using Ubuntu, you can reconfigure Docker easily by updating `/etc/docker/daemon.json` and restarting Docker:
    16  
    17  ```json
    18  {
    19      "storage-driver": "overlay2"
    20  }
    21  ```
