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.
