Benchmark between Symfony DependencyInjection ContainerBuilder AND League Container

<?php

require_once 'vendor/autoload.php';
use Symfony\Component\DependencyInjection\ContainerBuilder;
use Symfony\Component\DependencyInjection\Reference;


class Bar {}

class Foo
{
    public $bar;

    public function __construct(Bar $bar)
    {
        $this->bar = $bar;
    }
}

   
$bench = new Ubench;

$bench->start();


$container = new League\Container\Container;

$container->add(\Foo::class)->addArgument(\Bar::class);
$container->add(\Bar::class);

$foo = $container->get(\Foo::class);

var_dump($foo instanceof \Foo);      // true
var_dump($foo->bar instanceof \Bar); // true
$bench->end();
echo '<br>';
echo '<br>';
echo '<br>';
echo '<br>League';
// Get elapsed time and memory
echo  '<br>' . $bench->getTime() . '<br>'; // 156ms or 1.123s
echo $bench->getTime(true) . '<br>'; // elapsed microtime in float

echo $bench->getMemoryPeak() . 'Peak memory<br>';

echo $bench->getMemoryPeak(true) . '<br>'; // memory peak in bytes

// Returns the memory usage at the end mark
echo $bench->getMemoryUsage() . '<br>';


echo '<br>';
echo '<br>';
echo '<br>';
echo '<br>Symfony';
$bench->start();

$containerBuilder = new ContainerBuilder();
$containerBuilder
    ->register('bar', 'Bar');


$containerBuilder
    ->register('foo', 'Foo')
    ->addArgument(new Reference('bar'));

$foo = $containerBuilder->get('foo');

var_dump($foo instanceof \Foo);      // true
var_dump($foo->bar instanceof \Bar); // true
$bench->end();

// Get elapsed time and memory
echo  '<br>' . $bench->getTime() . '<br>'; // 156ms or 1.123s
echo $bench->getTime(true) . '<br>'; // elapsed microtime in float

echo $bench->getMemoryPeak() . 'Peak memory<br>';

echo $bench->getMemoryPeak(true) . '<br>'; // memory peak in bytes

// Returns the memory usage at the end mark
echo $bench->getMemoryUsage() . '<br>';

 Result:

League

Composer require

 "require": {

        "php": "^7.2.5",

        "league/container": "^3.3",

        "symfony/dependency-injection": "^5.0"

    },

    "require-dev": { 

        "devster/ubench": "~2.0.0"

    },

Multiple run gives mixed result. I decided to use league (https://container.thephpleague.com/).
