Very slow Symfony app

[jazithedev]

Hi,
I've god Symfony 3 application in Docker CE on my Windows 10 machine. Loading time of this app is about 4-5 seconds. Symfony initialization is about 600ms. I've got even opcache installed and that time is, still, HUGE!
What could be wrong? :(

Lowered application loading time by half when added

services:
    php:
        volumes:
            - /var/www/symfony/vendor

Hello,
This problem isn't related to this stack. But related to docker and the filesystem (see Shared Volumes Slow #188).

Unfortunately, there is no magic solutions for now
If you really want to mix Symfony, Docker and windows, you should limit the write operation between the host and the containers.

1. Move vendors outside the containers:

"config": {
    "bin-dir": "bin",
    "vendor-dir": "../vendor"
},

<?php
// previous
$loader = require __DIR__.'/../vendor/autoload.php';
// now
$loader = require __DIR__.'/../../vendor/autoload.php';

2. move cache+log folders

public function getCacheDir()
{
    if (in_array($this->environment, array('dev', 'test'))) {
        return '/dev/shm/application-name/cache/' .  $this->environment;
    }

    return parent::getCacheDir();
}

public function getLogDir()
{
    if (in_array($this->environment, array('dev', 'test'))) {
        return '/dev/shm/application-name/logs';
    }

    return parent::getLogDir();
}

See more about overriding dir structure (Symfony official documentation)

BTW, MacOS got the same problem: Docker for Mac #77.

@maxpou your new log path is on the host machine or on docker?
