Why is Laravel application working very slow on Docker? - php

Question

I am working on a quizz app. I have installed the Laravel app on docker and when I started working on the app I noticed that it takes very long for the app to load. It takes ~7-8s to load a page with a form which have 5 inputs.
I know that this waiting time is very long because a few weeks ago I installed a laravel application on docker that moves very quickly. But I can no longer use that one. I think it is possible that it is due to the .yml file and the Dockerfile, but I don't know what the installation problems would be.
I can not disable the Use the WSL 2 based engine (Windows Home can only run the WSL 2 backend) from Docker UI because I run W10 Home.

The DB is working fine, at a good speed.
The laptop power is not an issue because on the last app everything was running smooth and with no problems.

So I noticed that in WSL2 it is the filesystem which is an issue. If your project is on a folder in the Windows file system it will run much more slower than if you put the entire project into the Linux file system. Try moving your project into the linux system and see if it speeds it up.
For example, if your project is located in a windows folder like
C:\Projects\FooBar
Move it to the linux filesystem under WSL2 to something like:
/home/YouName/projects/FooBar
After you have done this - rebuild the container from the new location.
