Why aren't all my files cached using op apc code?

Question

I use APC (3.1.9) and the Zend Framework, however, only a bunch of files are cached (something like 10/400).

Do you have any ideas? I am using factory options to install debian.

EDIT: it looks like the only file that opcached is the one that I manually call with require ''; but those loaded by my autoloader are not. Any ideas?

here are the screenshots of apc.php

Files that get opcached

And index.php (ZF), where I require files and register the autoloader in Zend_Loader_Autoloader.

Answer 1

For some reason, apc.cache_by_default was set to OFF, my files did not receive caching correctly, which is logical given this configuration, however, I still do not understand why the ones I manually requested were actually cached.

Answer 2

Probably one of the biggest drawbacks of autoload is that the op cache does not cache autoload files, as one would hope (something about autoload being runtime or including / requires compilation time. Or not. I do not state that I understand this.). More details here .

While I have never tried, I wonder if manually adding your autoload file to the cache by calling apc_compile_file () in the autoloader can solve this problem?
