− | ; The number of child processes to be created when pm is set to 'static' and the | + | ; Specify the nice(2) priority to apply to the pool processes (only if set) |
− | + | ; The value can vary from -19 (highest priority) to 20 (lower priority) | |
− | + | ; Note: - It will only work if the FPM master process is launched as root | |
− | + | ; - The pool processes will inherit the master process priority | |

− | + | ; Set the process dumpable flag (PR_SET_DUMPABLE prctl) even if the process user | |
− | + | ; or group is differrent than the master process user. It allows to create process | |

+ | ; Choose how the process manager will control the number of child processes. | ||
+ | ; Possible Values: | ||
+ | ; static - a fixed number (pm.max_children) of child processes; | ||
+ | ; dynamic - the number of child processes are set dynamically based on the | ||
+ | ; following directives. With this process management, there will be | ||
+ | ; always at least 1 children. | ||

+ | ; pm.start_servers - the number of children created on startup. | ||
+ | ; pm.min_spare_servers - the minimum number of children in 'idle' | ||

+ | ; pm.max_spare_servers - the maximum number of children in 'idle' | ||
+ | ; state (waiting to process). If the number | ||
+ | ; of 'idle' processes is greater than this | ||
+ | ; number then some children will be killed. | ||
+ | ; ondemand - no children are created at startup. Children will be forked when | ||
+ | ; new requests will connect. The following parameter are used: | ||
+ | ; pm.max_children - the maximum number of children that | ||
+ | ; can be alive at the same time. | ||
+ | ; pm.process_idle_timeout - The number of seconds after which | ||

+ | ; served. Equivalent to the ApacheMaxClients directive with mpm_prefork. | ||
+ | ; Equivalent to the PHP_FCGI_CHILDREN environment variable in the original PHP | ||
+ | ; CGI. The below defaults are based on a server without much resources. Don't | ||
