Tecmint: Originally known as Zend Optimizer+, Opcache (introduced in PHP 5.5.0) is a powerful PHP extension built to enhance PHP performance thus boosting overall application performance. It is available as an extension through PECL for PHP versions 5.2, 5.3 and 5.4. It works by storing pre-compiled script byte-code in shared memory, thereby removing the need for PHP to load and parse scripts on each request.
