I just upgraded from PHP 5.3 to 5.6 and dumped APC for Zend Opcache. I really like what I'm seeing so far in terms of performance, but I'm confused about the configuration. First, I tried to increase the opcache.memory_consumption from the default 64 to 128, but after making this change, saving the file, and restarting PHP-FPM and Nginx it has not changed according to the GUI I'm using. Second, I noticed that I now have to restart PHP-FPM every single time I edit a PHP file if I want the changes to be applied. What is the best way around this, and will I be giving up any performance if I change it?
