PHP-FPM PHP-FPM tuning help!

PassMark - AMD Ryzen 9 3900X - Price performance comparison

Try this config:

 

i have a dedicated server which have 128 gb of ram and xeon processor with 1gbps bandwidth. I have installed centminmod on my server but the issue I am facing is that when my traffic raise to 3000 realtime the server stop responding.

What I am looking for what will be the configuration of php-fpm so it can handle 10000 realtime users
My configuration is this

global]
; Log level
; Possible Values: alert, error, warning, notice, debug
; Default Value: notice
log_level = warning
pid = /var/run/php-fpm/php-fpm.pid
error_log = /var/log/php-fpm/www-error.log
emergency_restart_threshold = 10
emergency_restart_interval = 1m
process_control_timeout = 10s
include=/usr/local/nginx/conf/phpfpmd/*.conf

[www]
user = nginx
group = nginx

listen = 127.0.0.1:9000
listen.allowed_clients = 127.0.0.1
listen.backlog = 65535

;listen = /tmp/php5-fpm.sock
listen.owner = nginx
listen.group = nginx
listen.mode = 0660

pm = static
pm.max_children = 3072
; Default Value: min_spare_servers + (max_spare_servers - min_spare_servers) / 2
pm.start_servers = 100
pm.min_spare_servers = 10000
pm.max_spare_servers = 15000
pm.max_requests = 10000

; PHP 5.3.9 setting
; The number of seconds after which an idle process will be killed.
; Note: Used only when pm is set to 'ondemand'
; Default Value: 10s
pm.process_idle_timeout = 10s;

rlimit_files = 65536
rlimit_core = 0

; The timeout for serving a single request after which the worker process will
; be killed. This option should be used when the 'max_execution_time' ini option
; does not stop script execution for some reason. A value of '0' means 'off'.
; Available units: s(econds)(default), m(inutes), h(ours), or d(ays)
; Default Value: 0
;request_terminate_timeout = 0
; Default Value: 0
;request_slowlog_timeout = 0
slowlog = /var/log/php-fpm/www-slow.log

pm.status_path = /phpstatus
ping.path = /phpping
ping.response = pong

; Limits the extensions of the main script FPM will allow to parse. This can
; prevent configuration mistakes on the web server side. You should only limit
; FPM to .php extensions to prevent malicious users to use other extensions to
; exectute php code.
; Note: set an empty value to allow all extensions.
; Default Value: .php
security.limit_extensions = .php

; catch_workers_output = yes
php_admin_value[error_log] = /var/log/php-fpm/www-php.error.log
php_admin_value[disable_functions] = shell_exec.

 

You can try something like:

pm = dynamic
pm.max_children = 80
; Default Value: min_spare_servers + (max_spare_servers - min_spare_servers) / 2
pm.start_servers = 32
pm.min_spare_servers = 16
pm.max_spare_servers = 64
pm.max_requests = 8000

 

Will this configuration will able to handle 10000 realtime users?

 

I think so....

 

just queries how you calculate this configuration will be right for 10000 users.

If I need to increase it more what will be the things i need to check

 

It is my personal estimation for your current server cpu cores+threads+ram...

There are a lot more factors to just say use that numbers and you will be able to handle 10000 users as it depends for example:

What each user does and what's the cost of each request for php.
How well is the server optimized.
How well is your software optimized

and a lot more.

But keep in mind that i am not an expert but you can easily test (if you don't have any other recommendations) my recommendation and if you don't like it just revert the edits and do a simple restart of phpfpm
