Our new server host unfortunately doesn't support OPcache. But does support Xcache.
I've read the available discussions & documentation concerning caching and moodle 2.8.
The bottom line seems to be that 2.8 doesn't appear to support the Xcache plugin.
Some o pre-release discussions I read between moodle' s developers concerning which cache plugins should be supported in the 2.8 release suggested that Xcache worked pretty well with tested pre-release versions.
My host needs Xcache to support another clent's web app. And he's not crazy about the idea of configuring PHP with redundant cache plugins.
Can I install and configure Xcache to work with moodle 2.8.5? Or should I abandon the idea of using caching altogether?
