Sample PHP5 FPM Pool configuration for high volume trafic

PHP5 FPM configuration for high throughput / trafic

I have a web project that required a lot of request per page load. I did not measure it exactly how many request, but it is probably around 50 - 100 requests. And I saw a few request timed-out especially when I cleared my browser cache or during a hard refresh.

So I tweaked my FPM pool configuration to the following setting to allow for more throughput:


[yourdotcom]

listen = /var/run/php5-fpm/yourdotcom.socket
listen.backlog = -1
listen.owner = www-data
listen.group = www-data
listen.mode=0660

; Unix user/group of processes
user = www-data
group = www-data

; Choose how the process manager will control the number of child processes.
pm = dynamic
pm.max_children = 80
pm.start_servers = 20
pm.min_spare_servers = 10
pm.max_spare_servers = 40
pm.max_requests = 1000

; Pass environment variables
env[HOSTNAME] = $HOSTNAME
env[PATH] = /usr/local/bin:/usr/bin:/bin
env[TMP] = /tmp
env[TMPDIR] = /tmp
env[TEMP] = /tmp

; host-specific php ini settings here
; php_admin_value[open_basedir] = /var/www/yourdotcom/htdocs:/tmp
