I run my XF1.5 forum on a server with PHP 7 + opcache enabled. Now I also would like to enable a caching mechanism for my xenforo installation. With PHP7 opcache is available, but not APC. As far as I can see memcache is not available in a stable version for PHP 7 So at the moment my only option is a file cache, right? What are your experiences? How do you cache with PHP7?
