Docker in MacOs is very slow – Phpmyadmin

I have this docker-compose.yml:

version: "3.1"
services:

    memcached:
      image: memcached:alpine
      container_name: universal-memcached2

    redis:
      image: redis:alpine
      container_name: universal-redis2

    mariadb:
      image: mariadb:10.4
      container_name: universal-mariadb2
      working_dir: /application
      volumes:
        - .:/application
        - "../data/db:/var/lib/mysql" # skasowac
      environment:
        - MYSQL_ROOT_PASSWORD=Haslo
        - MYSQL_DATABASE=sample
        - MYSQL_USER=user
        - MYSQL_PASSWORD=Haslo
      ports:
        - "8083:3306"


    webserver:
      image: nginx:alpine
      container_name: universal-webserver2
      working_dir: /application
      volumes:
          - .:/application
          - ./phpdocker/nginx/nginx.conf:/etc/nginx/conf.d/default.conf
      ports:
       - "8080:80"

    php-fpm:
      build: phpdocker/php-fpm
      container_name: universal-php-fpm2
      working_dir: /application
      volumes:
        - .:/application
        - ./phpdocker/php-fpm/php-ini-overrides.ini:/etc/php/7.3/fpm/conf.d/99-overrides.ini

    volumes:
        generated:
        var:
        static:

    phpmyadmin:
      image: phpmyadmin/phpmyadmin
      links:
        - mariadb
      environment:
        PMA_HOST: mariadb
        PMA_PORT: 3306
      ports:
        - '8081:80'

When I run my newest project in symfony 4 on it, it works very slowly… 🙁

I have new MacOs and Docker Desktop.
I’m currently learning the Symfony and Laravel framework, but this is very slow for Docker. It is not even working on it.

How can I repair it?

    As a matter of fact, Docker needs a plain Linux kernel to run. Unfortunately, Mac OS and Windows cannot provide this. Therefore, there is a client on Mac OS to run Docker. In addition to this, there is an abstraction layer between Mac OS kernel and applications (Docker containers) and the filesystems are not the same. Because of that, Docker runs on Mac OS slowly. You are not able to run the Docker on Mac OS like on Linux.

    If I need to give some instances about real use-cases. I have the same machine. So, I use Symfony 4 on Docker v18 on Mac OS Mojave. This is my Symfony total execution time on Docker. (Obviously, it depends on your frontend and database queries but I try to enlighten you for main logic.)

    • first time rendering 12000 ms
    • with Symfony cache: 344 ms
    • with Docker cache(:cached property of Docker for volumes): 195 ms

    As long as I use Symfony without Docker, the following is my total execution time.

    • without Docker, with Symfony cache: 82 ms

    Whereas, we could do some improvements to get better workspace. For example, you can use volumes like this,

    volumes:
        - .:/application:cached

    One option would be using http://docker-sync.io/ But you will not get the same performance as you would in a Linux-based machine.

    As mentioned in other answers, the issue comes down to the way Docker interacts with the file system on OSX.

    I found a great article on how to make things a lot faster on OSX:

    https://vivait.co.uk/labs/docker-for-mac-performance-using-nfs

    From the article, the real solution is to change the file system to use NFS, but as I know nothing about Docker (it was set up for me at work), I opted to use an option available in newer versions of Docker

    I added :delegated to all of the options under volumes in docker-compose.yml. After restarting my containers, every was nearly twice as fast as before. Not as fast as native, but fast enough.

    Example from article:

    app:
    build:
        context: .
        dockerfile: ./docker/app/Dockerfile
    working_dir: /app
    user: "www-data"
    volumes:
        - ./:/app:delegated
        - ./:/another_folder:delegated

    The NFS example is quite long and requires basically copying half of the article so I won’t add it in, but this :delegated solution is good place to start.

    Use Mutagen to sync volumes

    It’s a known issue that Docker for Mac is slow when using shared volumes containing a big amount of files, see https://github.com/docker/for-mac/issues/77.

    So, some workarounds came like :cached and docker-sync. However it’s not totally satisfactory because it’s still slow compared to native (Linux) and docker-sync consumes a lot of resources when syncing.

    That being said, there is a good alternative, not to say perfect, which is Mutagen. It’s almost as fast as native shared volumes with Linux!

    A benchmark is available:

    Source: article on Medium

    I created a full example for a Symfony project to show how to use it, but it can be used for any type of project in any language.

    I recommend using Parallels (the best virtualisation for macOS). Then:

    1. Install Linux
    2. Install ssh server
    3. Install docker

    If you use VSCode, you can install SSH extension and it is fast enough for editing files. You can also access your website on macOS via virtual machine’s IP address.

    This is know. Issue with docker and the Mac… they are not best buddies, but they can play with each other.

    Add :cached to the volumes and the slowness will be manageable.

    To anyone still having this issue, I have read a post on gitHub by StefanPrintezis here.
    Basically, when you’re not debugging, turn off xDebug.
    It worked like a charm for me.

    Configuration : Macbook Pro 2018, PHPStorm 2021.3.1, Docker Desktop 4.5.0 (74594) with 2 CPU / 4GB RAM. Using default volume config.

    Using VirtioFS significantly improves Docker performance on macOS.

    macOS 12.5 and Docker Desktop 4.15

    Docker Desktop Preferences > General

    [x] Use Virtualization framework (select this option)
Choose file sharing implementation for your containers: pick VirtioFS

    macOS 12.3 (Intel) or 12.2 (Apple M1) and Docker Desktop 4.6, you can enable the experimental feature :

    To enable virtiofs in Docker Desktop:

    Ensure that you are using Docker Desktop version 4.6, available here

    • Navigate to ‘Preferences’ (the gear icon) > ‘Experimental Features’
    • Select the ‘Use the new Virtualization framework’ and ‘Enable VirtioFS accelerated directory sharing’ toggles
    • Click ‘Apply & Restart’

    Speed boost achievement unlocked on Docker Desktop 4.6 for Mac – March 16 2022

    On a MacBook Pro 2019, 2.6 GHz 6-Core Intel Core i7, even simple commands such as docker ps execute in less than a second. It used to take 3 seconds before.

    I had the same issue, where requests could take upwards of 20 seconds!

    The fix was to disable "Use the new Virtualization framework"

    enter image description here

    I also tried the "VirtioFS" experimental option which made it faster but it would constantly lock up. Disabling them both fixed all issues.
