I recently setup an OwnCloud server running on SLES 12. It works great, but I noticed that for performance reasons, OwnCloud is recommending that I implement caching for PHP. For PHP 5.5, they recommend using APCu which they indicate should be available in most distros. Of course, I can't find that in SLES 12. They also suggest using APC or Memcached, neither of which I can find in SLES 12. Is there a PHP-APCu package officially available for SLES 12? What would be the recommended solution for this on SLES 12? I did install PHP-OPCache, but that doesn't appear to be what is needed or is not supported (I'm really a n00b with PHP here). I did find an unsupported package of APCu for SLES 12, but I wasn't sure if I should go that route or not.
Here is the link to the Owncloud documentation on caching:
