title: Magento: Mage::registry('current_product') efficient?
body: <p>This is probably something obvious if you know the process behind it.. But when you use <code>Mage::registry('current_product')</code> on a product page, for example, are you merely referencing something that is already "loaded" or are you loading it every time you run that line of code?</p>
  
  <p>In other words, which is more efficient? (pseudocode below)</p>
  
  <pre><code>Mage::registry('current_product')-&gt;getName() over and over
  </code></pre>
  
  <p>Or...</p>
  
  <pre><code>$temp = Mage::registry('current_product') then
  $temp-&gt;getName() over and over
  </code></pre>
