'value' => $stats['num_cached_keys'] - $stats['num_cached_scripts'], |
From what I understand, the difference between num_cached_keys and num_cached_scripts does not equal the amount of wasted keys.
OPcache Keys are all the relative and absolute paths leading to a script.
So there are naturally more Keys than there are Scripts, the difference here however is not the amount of wasted keys.
