Optimize Nginx + PHP-FPM for 5 million daily pageviews

I run a few high-volume websites which together generate around 5 million page views per day. Every page on this sample just uses PHP it was on a PHP page that doesn't have any database calls which makes me to configuretion NGINX, PHP-FPM .

I have 3 NGINX servers running behind a load balancer. database is separate on a cluster. I Optimize our configuration files for nginx and php-fpm as well as our current RAM usage and PHP-FPM status.

Specs for each NGINX Server:

OS: CentOS 7
RAM: 128GB
CPU: 32 cores (2.4Ghz each)
Drives: 2xSSD on RAID 1
RAM Usage (free -g)
