My setup @ debian 6-testing is: nginx 1.1.8 + php 5.3.8 + php-fpm + APC 3.1.9
Because i use automatic deployment with apc_clear_cache() after deploy, my target is to set up APC to cache all my project (up to 612 php files smaller than 1MB) without files changes checking.
My confs:

I have multiple instances of APC running on my server with similar configurations (albeit with different cache sizes. However, one of the instances is performing extremely poorly, and I have no idea why (100% cache fragmentation, high miss rate).
