If you need to calculate and change these values based on the amount of memory on the system the following command will help us to determine the memory used by each (PHP-FPM) child process:<\/p>\n

ps -ylC php-fpm --sort:rss<\/pre>\n
pm.max_children<\/strong>\u00a0can be calculated as:<\/p>\n
pm.max_children = Total RAM dedicated to the web server \/ Max child process size<\/pre>\n
The server has 8GB of RAM, so:<\/p>\n
pm.max_children = 6144MB \/ 85MB = 72<\/pre>\n
You need to take into account any other services running on the machine while calculating memory usage.<\/p>\n
Then change the settings as follow:<\/p>\n
pm.max_children = 70  \r\npm.start_servers = 20  \r\npm.min_spare_servers = 20  \r\npm.max_spare_servers = 35  \r\npm.max_requests = 500<\/pre>\n
