It shows: cached files: 2. But what is "hits"? Hits are when the requested page was found in the cache, misses are when it wasn't. Actually hits more accurately refers to "how many objects were already in the cache and were used" so it might be counting one page as multiple objects. You might be able to run a number of tests with some hello world examples and clearing the cache. Maybe the page you're hitting is including other pages or scripts and that is counting as multiple objects.

On top of that once the store is full requests to store information within the cache fail until there is once more sufficient space. Because of this it is recommended that you regularly purge or restart APC. Also recommended is to map a secondary application cache instance to any definition with the APC mapped. This ensures that if it does indeed full up that an alternative cache is available.

Its also worth noting for this those using Linux that there is usually a php5-apc package that can be installed very easily. If you have installed PHP under Linux through a package manager then this will be by far the easiest way to proceed.
