i am using nginx with php-fpm (on centos) and a while ago i found a variable in one of the various config files that determines whether the server checks for the existence and/or change status of each of the served php files (as i comprehend what was occurring there). i read that one setting increases server performance and so i chose that setting. i found i needed to restart php-fpm service manually for changes that i made to my website's code to be picked up by nginx and served.
i recently upgraded php and this setting is no longer as it was and i am not recalling what the parameter name/token is.. so i am not able to re-activate it. does anyone know what the variable is? thanks
