XF 1.2 How to properly enable memcached and apc?

[rdn]

This is my config right now:

<?php

// Cache
$config['cache']['enabled'] = true;
$config['cache']['cacheSessions'] = true;
$config['cache']['frontend'] = 'Core';
$config['cache']['frontendOptions'] = array('caching'  =>  true,
                                            'automatic_serialization' => true,
                                            'lifetime'    => 3600,
                                            'cache_id_prefix'  =>  'phcn_'
);
// MemCache
$config['cache']['backend'] = 'Memcached';
$config['cache']['backendOptions'] = array(
    'compression' => false,
    'servers' => array(
        array(
           
            'host' => '127.0.0.1',
            'port' => 11211,
        )
    )
);
// End of Memcache
$config['cache']['backend'] = 'Apc';

But I cannot see it working on my memcache admin:

$config['cache']['enabled'] = true;
$config['cache']['frontend'] = 'Core';
$config['cache']['frontendOptions']['cache_id_prefix'] = 'xf_';
$config['cache']['frontendOptions']['automatic_serialization'] = true;
$config['cache']['cacheSessions'] = false;
$config['cache']['backend']='Memcached';
$config['cache']['backendOptions']=array(
      'compression'=>false,
      'servers' => array(
              array(
                      'host'=>'127.0.0.1',
                      'port'=>'11211',
                      'persistent' => 'true'
                )
      )
);

I've added this but getting ErrorException: Memcache::get(): Server 127.0.0.1 (tcp 11211) failed with: Connection refused (111) - library/Zend/Cache/Backend/Memcached.php:180 errors.

I've opened the port 11211 by the way.

so with the various methods of caching being discussed in this thread, what sort of sustained load can you guys experience on your server using a tool like apachebench? how many successful requests/second with the various caching mechanisms?

and have you installed the pecl-memcache extension?

Apparently I have.

I'm getting these errors:

[MattW]

can you do a ps -ef | grep memcache on the server?

 

[Brent W]

Can someone explain what automatic serialization does?

 

[Ranma1981]

Hello,

when I enabled the cache, using "Libmemcached", after few minutes I receive this error:

An exception occurred: Memcached::get(): could not read long value, too big in /var/www/clients/client0/web2/web/forum/library/Zend/Cache/Backend/Libmemcached.php on line 166

1. XenForo_Application::handlePhpError()

Do you have idea of reason?

Thanks

No need to configure it on config.php, Zend Opcache automatically does its job.
