title: Composer out of memory
body: <p>After installing sylius (standart)</p>
  
  <pre><code>composer create-project -s alpha sylius/sylius-standard acme // its OK
  composer update // ERROR
  
  Fatal error: Allowed memory size of 1073741824 bytes exhausted (tried to allocate 58720256 bytes) in phar://C:/ProgramData/ComposerSetup/bin/composer.phar/src/Composer/DependencyResolver/RuleSet.php on line 73

  <p>Ref Ask in GitHub (<a href="https://github.com/Sylius/Sylius/issues/6854" rel="nofollow noreferrer">#6854</a>)</p>
  
  <p>I have increased memory_limit (php) to 1G, 3G, -1 and same results.</p>
  
  <pre><code>My sistem:
  Windows x64
  Processor Phenom x955 x4
  RAM 4GB
  Composer 1.2.2
  PHP 7 (I tried with 5.6 too)
  </code></pre>
  
  <p>The ask: Which server would need minimally to implement sylius?</p>
  
  <p>Or will this problem only happen with composer?</p>
