Centos 5.5 resource usage
I've just finished setting up a test web server using Centos 5.5, and I find the resource usage quite high. With a similar setup my older redhat 9 takes up half this even with some user activity. There isn't any user activity except myself configuring & testing.
It's using almost 500 MB of RAM, and I need to know if this is normal before I set this into a production environment. It also seems to take up more RAM the longer the uptime has gone. On first boot it's maybe ~200 MB or less, and after a few days it'll be up to 500+.
I'll list my config, and then if there's anything else you guys need please let me know, thanks!
Centos 5.5 with everything updated (using yum update).
Apache, php, mysql, bind - all latest versions downloaded from the websites of these groups, and APF firewall with default settings and development mode enabled. There's also sendmail enabled but not yet configured.
No other software has been installed or touched, except a few services like cups which I stopped on boot with chkconfig.
If there's other info you need please tell me what it is and the best way for me to get it to you. Thanks!
