    Which one performs better?

    I got 2 options from wordpress plugin directory.

    One that support Memcached and Memcache pecl but outdated plugin (last update 1 year ago / not tested with latest WP version).
    and other one that is actively developed/updated plugin which is also mostly recommended plugin but only support Memcache pecl module.

    that's because Centmin Mod uses latest dev version of memcache PHP extension from an unofficial git repo branch specific for PHP 7 support :) Probably same source where Remi repo one came from ?

    Remi uses the php-memcached, that one is php-memcache. Two different extensions.

    oh yes.. both memcached and memcache on Centmin Mod are PHP 7 supported as i use unofficial/not main github repo branches - so that's what I am suggestion Remi repo has done too :)

    On one of the forums I admin, I recently upgraded the server to PHP7 and now seeing a lot of these errors:

    XF 1.4 - Registration problem. "The field 'xxxxxxxx' was not recognised." | XenForo Community

    Thanks to @RoldanLT for debugging that it's most likely a memcache issue.

    Currently I have the following for the xenforo config.php on that site:
    Code:
    $config['cache']['enabled'] = true;
    $config['cache']['frontend'] = 'Core';
    $config['cache']['cacheSessions'] = true;
    $config['cache']['frontendOptions'] = array(
            'caching' => true,
            'cache_id_prefix' => 'mvc_xf_',
            'automatic_serialization' => true,
            'lifetime' => 0
          );
    
    $config['cache']['backend'] = 'Libmemcached';
    $config['cache']['backendOptions'] = array(
            'servers' => array(
                array(
                    'host' => '127.0.0.1',
                    'port' => 11211,
                    'persistent' => 'true',
                    'weight' => 1
                )
            )
      );
    
    @RoldanLT what memcache PHP library are you using on your PHP 7 box?

    @eva2000 should I switch to using memcached rather than libmemcached since this is a PHP7 box? I saw your note above about memcached being based on libmemcached, not sure though if that means I need to use memcached rather than libmemcached or not.

    memcached php extension uses libmemcached, so that is correct

    but xenforo 1.4 doesn't fully support php 7. For php 7 you need to be using xenforo 1.5 branch.
