A script to tune PHP-FPM

PHP-FPM tuner

Simple script that helps tuning PHP-FPM.

❯ php php-fpm-tuner.php

pm.max_children = 11
start_servers = 3
min_spare_servers = 3
max_spare_servers = 8

The script calculates pm.max_children based on available free memory and memory used for each worker (it is either determined from currently running workers or php.ini memory limit). start_servers, min_spare_servers, and max_spare_servers are taking both memory limits and CPU cores available into account.
