My OS is CentOS7 and I am using PHP7-FPM with nginx

Server specification are below

Processor: Intel Xeon E5-1620v2

Sever Ram: 64GB DDR3

My current fpm configurations are below

pid = /run/plesk-php70-fpm.pid

error_log = /var/log/plesk-php70-fpm/error.log

log_level = error

emergency_restart_threshold = 10
emergency_restart_interval = 1m
process_control_timeout = 10s

listen.backlog = 65535

;[php-fpm-pool-settings]
pm = ondemand
pm.max_children = 2000
pm.process_idle_timeout = 10s
#pm.max_requests = 10000

#pm = dynamic
#pm.max_children = 5000
#pm.start_servers = 50
#pm.min_spare_servers = 20
#pm.max_spare_servers = 70
#pm.max_requests = 10000
