I want to move to VPS and install apc cache. I found in this thread how to enable it https://xenforo.com/community/threads/tip-use-apc.6456/ My questions are: 1. I have this code in the config.php that enables simple caching, should I remove it? Code: $config['superAdmins'] = '1'; $config['cache']['enabled'] = true; $config['cache']['backend'] = 'File'; $config['cache']['backendOptions'] = array('cache_dir' => '/home2/morethb8/public_html/bettingforum/internal_data/cache'); $config['cache']['frontend'] = 'Core'; $config['cache']['frontendOptions'] = array('caching' => true, 'automatic_serialization' => true, 'lifetime' => 1800 ); 2: I also have mods for caching- xen cache and bd-cache. Should I disable some of them too or no?
