Default High Memory usage

Hi,

My server has 4GB of memory, but the total commited memory is a lot higher (6.2GB).

I followed the guid : The Perfect Server - Ubuntu 12.04 LTS (nginx, BIND, Dovecot, ISPConfig 3)

How to get my memory usage better ?

Code:
top - 14:01:36 up 3 days, 23:29,  3 users,  load average: 0.24, 0.22, 0.17
Tasks: 419 total,   1 running, 414 sleeping,   4 stopped,   0 zombie
Cpu(s):  0.0%us,  0.1%sy,  0.0%ni, 99.6%id,  0.2%wa,  0.0%hi,  0.1%si,  0.0%st
Mem:   4040628k total,  3803656k used,   236972k free,   180004k buffers

Default

On the Options tab of your web sites in ISPConfig, lower the PHP-FPM values:

PHP-FPM pm.max_children: 10
PHP-FPM pm.start_servers: 2
PHP-FPM pm.min_spare_servers: 1
PHP-FPM pm.max_spare_servers: 5

ISPConfig 3.0.5 will have lower values by default, plus the option to select the PHP-FPM mode (static, dynamic, or ondemand).

Default [Resloved] High Memory usage

Thanks Falko, that did it.

Memory usage dropped instantly.
Don't know why, but these setting came as default when setting up ISPConfig.

These are the default settings in 3.0.4.x, but they have been lowered in 3.0.5.
