This would be a great how-to. Teach us how to lower memory and cpu usage yet, keep a balance with security and peice of mind. Which brings to this question. What services can I disable and enable so that my "VPS" doesn't use so much memory? I commited my VPC to use 256mb of memory yet it persists in using 300mb. I set the swapfile the same as the tut for fedora 3 but I don't think it uses it . Does it really need 300mb? Can I lower it to 200mb? Does Gnome use memory even you aren't logged into the the gui?
