Please help me to understand where is difference between APC and APCu lies. While inspecting CentOS web-server (set up not by me) found that it has APCu 4.0.2 installed and phpinfo(); reports that APC Emulated.
It was bit confusing, anyway tried to use settings for normal APC in php.ini
apc.enabled=1
apc.shm_size = 768M
apc.cache_by_default = 0
apc.filters="+domain.com,+anotherdomain.com"
apc.stat = 0
apc.max_file_size=2M
Then checked apc.php status page and it revealed that only apc.shm_size changed, but no cache entries for selected domains. So how can i adapt APCu to cache selected domains as APC did ?
