magento

Hi,

i am a noob with servers. I have a centos5.5 vps with 512mb ram. My goal is to have it host just one magento store. I've installed Magento on the server without any control panel, by just installing lamp myself and whatever php extensions were necessary to get Magento to install.

As soon as i visit my magento store, suddenly the ram on the vps is almost completely used, with only about 100mb left. Please see this screenshot of htop taken after just myself visited the website.

As you can see there's only around 100mb left. Is that normal? I'm wondering if i might have done something stupid with the server that makes it very resource hungry. I installed apache from the centos base repo, php version 5.3 from the ius repository and mysql 5.1 also from ius repo. I haven't changed any of the default config files for any of these except to make memory_minimum 256 in php.ini. Is there anything i can do to make more ram free?

I'm clueless but i see each Apache daemon is using 8% of available ram, and AFAIK each visitor needs one Apache daemon. So i would run out of ram with just a handful of visitors. Thanks for your advice.
