Adjusting child processes for PHP-FPM (Nginx)

When setting these options consider the following:

How long is your average request?
What is the maximum number of simultaneous visitors the site(s) get?
How much memory on average does each child process consume?

Determine if the max_children limit has been reached.

sudo grep max_children /var/log/php?.?-fpm.log.1 /var/log/php?.?-fpm.log
