#1 What exactly is cached with $config['cache']['enabled'] = true; enabled? #2 How is that different from BD cache? https://xenforo.com/community/resources/bd-cache.2763/ #3 Xenforo can use APC cache, memcached, or file cache I keep hearing APC has issues with 5.5+ so I'm going to cut that out as an option That leaves memcached and filecache (am I missing anything? Does it support redis?) Memcached is clearly faster than standard file cache because file cache is on disk while memcached is in ram What I would like to know, is memcached faster than tmpfs filecache? I'm primarily used to a wordpress environment and people consistently say tmpfs is faster than using memcached as a backend for pagecaching If not, on a single box, why would you use memcached?
