When php-fpm and mysqld work, it will consume more RAM, especially php-fpm. Mine's currently around 80MB. You can lookup using google for more RAM optimization tutorial.

it's likely spawning more processes to handle the amount of requests you are getting or you installed a opcode cache which will increase RAM use.

How do we know if the node is running Centos 6? and why will it use less ram?

nginx is a webserver. use it like you would apache/httpd or lighttpd.

It will use less ram because the version of OpenVZ included with CentOS 6 changes the memory management to be more like a real servers. To tell if it is on a CentOS 6 node, just check if the buffers/cache are not 0 in free -m.

free -m:

does this mean that it is a centos 6 node?

**dmmcintyre3** · 08-03-2011, 04:58 AM

No. If the buffers/cached on the top is non zero it's using the newer openvz.

So 0 = Centos 6
Not 0 = newer openvz.

EDIT: Oh! I thought that you meant
