Using ZendOptimizer as cache engine?

You don't, it will just work as it's a OPCode Cache, so you don't need to configure anything in XenForo to use it. If you want to use the backend cache, you will need to install Memcache/uAPC to work.
Hey Matt. So what will be the config.php settings for using zend optimizer? Cache=off?

Ah, I thought you were referring to the new version with PHP5.5

I've never used the older Zend Optimizer, so wouldn't know unfortunately.
