title: Is using PHP accelerators such as MMCache or Zend Accelerator making PHP faster?
body: <p>Does anybody have experience working with PHP accelerators such as <a href="http://turck-mmcache.sourceforge.net/" rel="noreferrer">MMCache</a> or <a href="http://www.zend.com/en/" rel="noreferrer">Zend Accelerator</a>?  I'd like to know if using either of these makes PHP comparable to <em>faster</em> web-technologies.  Also, are there trade offs for using these?</p>
