Hi,

I have been running a website for more than one year on CentOS 6.6, Nginx1.6.2, php-fpm5.6.5remi with success. Until now I wasn't able to challenge the default configuration of all these packages, because I didn't want to test on my production server directly.
The performance was not that great but it was fine.
Recently, I rented another server and I can now test all the stack.
When playing with this new server, I discovered that there was an apcu-panel package available to get some idea about the apc cache performance.
When displaying the apcu-panel, I saw that nothing was really cached!
I can give all the configuration files but it's not going to be very useful because I didn't change the default configuration for most of the files.
Also, I repeated the installation several times and got the same result.
The apcu-panel shows that apcu is working fine but no files are cached.
The only special detail in my configuration is that I set my Nginx root directory in opt instead of var (SELinux context files have been set with semanage).
As I don't see how to investigate this problem further, I'm asking for help ...

Thanks in advance.
