title: PHP Performance/bytecode caching
body: <p>I'm currently studying to take the Zend exam and some things are not clear to me. Zend requires that we know the "<strong>Performance / bytecode Cacing</strong>." Reading the documentation on php.net I could not find anywhere.</p>
  
  <p><a href="http://www.zend.com/en/services/certification/php-5-certification/" rel="nofollow">http://www.zend.com/en/services/certification/php-5-certification/</a></p>
  
  <p>Can anyone explain me what is the <strong>Performance/bytecode caching</strong> and where i can read more about that...</p>
  
  <p>Also he want to know "Config"... I'm not sure what zend exactly is meant?</p>
  
  <p>Thanks...</p>
