PHP OPcache

We strongly recommend you verify the PHP OPcache is enabled for performance reasons. The OPcache is enabled in many PHP distributions. To verify if it is installed, see our PHP documentation for CentOS or Ubuntu.

If you must install it separately, see the PHP OPcache documentation.

PHP settings

We recommend particular PHP configuration settings, such as memory_limit, that can avoid common problems when using Magento.

For more information, see our Required PHP settings.
