Speed comparison of network_mode: host with internal network

Docker Engine Compose
,
1

Hello,
I have MariaDB installed on the host and connect to it using the following configuration:

network_mode: host
    environment:
      DB_HOST: host.docker.internal
...
    extra_hosts:
      - "host.docker.internal:host-gateway"

Does using a database as a container and internal network have a significant impact on speed?

Please share your experiences.

Thank you.

It takes about 10 seconds to load each page of the website. What do you think is the problem? Is there something wrong with the Docker configuration?
