Symfony 3 and Docker (nginx, php7.1-fpm mysql8) Performances low on Windows - nginx

Question

I'm using Docker to work on Symfony 3 project, Here is the following stack :
-Custom Php7.1FPM here's the DockerFile :
FROM php:7.1.0-fpm
MAINTAINER xxxxx xxxxxx <xxxx.xxxxxx#gmail.com>
ENV PHP_APCU_VERSION 5.1.8
ENV PHP_XDEBUG_VERSION 2.5.0
RUN apt-get update \
&& apt-get install -y \

&& chmod +x /usr/local/bin/composer
last nginx image
mysql:8.0.0
I use docker-compose to build those 3 containers, here's the docker-compose.yml :
front:
image: nginx
ports:
- "81:80"
links:
- "engine:engine"
volumes:
- ".:/home/docker:ro"
- "./docker/front/default.conf:/etc/nginx/conf.d/default.conf:ro"
engine:
build: ./docker/engine/
volumes:
- ".:/home/docker:rw"
- "./docker/engine/php.ini:/usr/local/etc/php/conf.d/custom.ini:ro"
links:
- "db:db"
working_dir: "/home/docker"
db:
image: mysql:8.0.0
ports:
- "3306:3306"
environment:
- MYSQL_ROOT_PASSWORD=pwd
- MYSQL_USER=myUSer
- MYSQL_PASSWORD=pwd
- MYSQL_DATABASE=bddProject
The first time without cache the time is 1700 ms :
And the time with cache is :
The half time is initialisation time :
So What kind of problem could slow the page render of my project ?
Docker last version and 2 Go with Windows Hyper-v system.
Thank you for your help.
So i make an other image without xdebug ant the result is the same
(700ms with cache) :
My DockerFile :
FROM php:7.1.0-fpm

So it's the window's management of Docker volume which make that, so #Geoffrey Brier you know if Microsoft has planned to improve this performance problem ?
Is there a soft or other to improve that ?
Thank you for your help.

Answer 1

As far as I can see there are two things that are responsible for those performances :
Xdebug
Windows : it's no troll but it's a well known problem that the way your containers volumes are handled by Docker on Windows is not as efficient as on Linux.
You have three solutions : struggle to find a method that slightly improves the performances, use Linux (in a VM for instance) or deal with it :)
