title: Is the more the better for PHP memory_limit?
body: <p>In PHP, i am oftenly facing memory limit problem. Especially with highly resource integrated systems like Drupal, etc.</p>
  
  <p>What i want to know here is:</p>
  
  <ul>
  <li>Is it good to have very high php memory limit like 2GB?</li>
  <li>Is there any major drawback?</li>
  </ul>
  
  <p><strong>Edited:</strong></p>
  
  <blockquote>
    <p>As a scenario, for example in Drupal, it NEEDS so much memory while we
    CLEAR the CACHE via Web Panel (Not by Drush or any script). So even for
    this case only, i am definitely needing high-limit around 512MB currently.</p>
