Docker Wordpress super slow

[admin]

I have Wordpress running inside Docker, for local development, and it's super slow. My docker-compose.yml looks like this:

version: '3.3'

services:
  db:
    image: mysql:5.7
    volumes:
      - ./db_data:/var/lib/mysql
      - ./dbconfig.cnf:/etc/mysql/conf.d/custom.cnf
    restart: always
    ports:
      - "3308:3306"
    environment:
      MYSQL_ROOT_PASSWORD: root_password
      MYSQL_DATABASE: wp_database
      MYSQL_USER: db_user
      MYSQL_PASSWORD: some_secure_password

  wordpress:
    depends_on:
      - db
    image: wordpress:latest
    ports:
      - "80:80"
      - "443:443"
    restart: always
    volumes:
      - ./wp-content:/var/www/html/wp-content
      - ./.htaccess:/var/www/html/.htaccess
      - ./wp-config.php:/var/www/html/wp-config.php
      - ./logs/debug.log:/var/www/html/wp-content/debug.log
volumes:
  db_data: {}
  wp_content: {}

As far as I read online, it might be the reason I am mounting the

wp-content

volume, which causes super slow page loading (takes like half a second to load each file, e.g. a jquery file, and it has to load a ton of files for one page).

Is there a solution for this? I read about NFS, but it didn't work for me to configure NFS with docker-compose, somehow I keep getting "permission errors". On the other hand, the Docker interface of macOS already shows me a "Shared folder" tab but I don't know whether I am using those shared folders at the moment or just mounting them again.

Any help is appreciated.
