title: PHP PECL Gnupg extension takes more time
body: <p>I have implemented the PECL extension <a href="http://php.net/manual/en/book.gnupg.php" rel="nofollow">gnupg</a> <strong>(pecl.php.net/gnupg-1.3.6
  )</strong> for password encryption and decryption in my project. </p>
  
  <p>During a load test of 500 + users the methods $this->gnu->setarmor(0); and  $this->gnu->adddecryptkey() consumes more time than the other PHP processings.</p>
  
  <p>Ex: If an average login time takes 10 secs, the processing time for the gnupg alone takes 5 to 6 secs.</p>
  
  <p>Just wondering why the gnupg alone takes more time during a load test. </p>
  
  <p>Any suggestions?</p>
