From the developer:
Zend Optimizer is loaded as a PHP engine extension. This extension
automatically optimizes PHP scripts, and transparently detects and loads
encoded files. The Zend Optimizer boosts PHP performance by going over the intermediate code generated by the standard Zend run-time compiler and optimizing it for faster execution.
