PHP Pest (with Laravel) tests running very slow in OSX Docker - php

Question

I was developing an app locally using Laravel. For testing I was using Pest and tests were running fast, really fast. That was until I decided to Dockerize my app, now tests are running pretty slow.
What it used to run in 3 seconds now it's running in over a minute.
Here's my Dockerfile:
FROM php:8.1.12-fpm
ARG uid=1000
ARG user=macgiver
RUN apt-get update && apt-get install -y \
git \
curl \
libpng-dev \
libonig-dev \
libxml2-dev \
zip \
unzip
# Install and enable xDebug
RUN pecl install xdebug \
&& docker-php-ext-enable xdebug
RUN apt-get clean && rm -rf /var/lib/apt/lists/*
# Install php modules required by laravel.
RUN docker-php-ext-install pdo_mysql mbstring exif pcntl bcmath gd
# Create system user to run Composer and Artisan commands.
RUN useradd -G www-data,root -u $uid -d /home/$user $user
RUN mkdir -p /home/$user/.composer && \
chown -R $user:$user /home/$user
# Install composer
COPY --from=composer:latest /usr/bin/composer /usr/bin/composer
# Set working directory
WORKDIR /var/www
USER $user
and this is my docker-compose:

Any ideas?
