Questions tagged [opcache]

OPcache is a PHP opcode cache introduced in PHP 5.5 (and is also available as a PECL extension for PHP 5.2+). It is based on the Zend Optimizer+

The Zend OPcache provides faster PHP execution through opcode caching and optimization. It improves PHP performance by storing precompiled script bytecode in the shared memory. This eliminates the stages of reading code from the disk and compiling it on future access. In addition, it applies a few bytecode optimization patterns that make code execution faster.

Also see the OpCache Readme, the PHP OPcache documentation and the PECL OPcache page.
