Speeding up XenForo: turning on caching

By default, caching is disabled in XenForo. Caching is done using the Zend Framework, so a wide variety of caching systems are available. And turning it on is very simple.

Turn on

To enable it, add the following to /library/config.php:

$config['cache']['frontend'] = 'Core';
$config['cache']['frontendOptions'] = array('caching'   =>  true,
                                            'automatic_serialization' => true,
                                            'lifetime'    => 1800
);

FrontendOptions help.

Next we need to choose which caching mechanism to use. Add the configuration we need to config.php:

Memcached:

$config['cache']['backend'] = 'Memcached';
$config['cache']['backendOptions'] = array(
    'backendOptions'=>array(
            'servers' =>array(
                            array(
                                'host' => 'localhost', // your memcached server ip /address
                                'port' => 11211        // memcached port
                            )
                        ),
             'compression' => false
     )
);

APC:

$config['cache']['backend'] = 'Apc';
$config['cache']['backendOptions'] = array();

File system:

$config['cache']['backend'] = 'File';
$config['cache']['backendOptions'] = array('cache_dir'  => 'D:\xampp\xampp\htdocs\xf\upload\library\cache');

Of course, the directory must be writable.
