Which PHP Type to set on webserver config

[mawerick]

I need expert opinion about Webserver config / PHP Type

Situation:
Kloxo MR on dedicated server with 8gb RAM, 3.2ghz dual core CPU. CentOS 6.
Server is personal, not for resell. Only I administrate it.
Host 5,6 websites(like 9gag), with huge image bandwidth traffic.

My question is, which PHP type better fits for me:

mod_php_ruid2
mod_php_itk
suphp
suphp_event
suphp_worker
php-fpm_event
php-fpm_worker
fcgid_worker

1. Prepare with php-fpm_event
2. Separated each domain to each client
3. Set 'fastcgi childrens' to '12' - '24' for every clients in 'limit'
4. Change 'php-fpm type' to 'dynamic' in 'php configure' for every client

Mustafa,

What about the situation where server is 4GB RAM / 4Cpu and / php56m / fpm_event

Clients count is 15, with 25 websites at all

out of those 15 clients 2 have average traffic, rest have very small traffic ,

but when i ran "top" i see each client has 4 "php-fpm" processes . Thus 60 php-fpm processes running (i assume consuming memory?)

could you advise how i can tune this model ? maybe switching to another?

Thanks

By default, max php-fpm/fastcgi children is 6 (as the same as 'unlimited') where min-spare is 1/6 x max children and max-spare is 1/3 x max children. But, min and max-spare no less than 2.

In your situation, try decrease max children to 4 for low traffic and stay to 6 or more to high traffic. Max sure using 'ondemand' for 'php-fpm type' for low traffic.

I'm not sure how to implement point 2,3 and 4. Can i see somewhere manual/instructions or explain my in short in which menus/config files to change.

Someone to help ?
