Laravel request/response time very slow on Docker Laravel 8 - php

Question

Does anyone have any idea why the request time of my Laravel project is running very slow? I'm running the project on Docker and I use a Dockerfile and docker-compose.yml. I'm also using nginx
I have tried multiple things like Eager loading and artisan optimize but none of those seems to work.
I'm running this on a laptop with an i7-9750H and 16gb RAM.
This what my debugbar says:

That's not slow.
20MB in 1.7s is about 12MB/s, with overheads that's pretty quick.
The route you're hitting is returning heaps of data, probably more than you expect, and that's why it looks like it's running slow.
