Just got a new dedicated server. It has 2GB Ram and Dual Core processor. I logged on Shell and ran the 'top' command. The bit that is worrying me is the used memory. Its showing about 1.8GB of 2GB in use. Hows that possible I dont even have a single site on the server yet.. can someone clarify ..
Memory on Linux works differently than on Windows. It may show you it has a lot used, but don't worry, there's memory left. Unless you start to see swap being used, there's no need to worry.
aha.. so thats how linux does things ? no wonder most peeps dont like it. cant they just be damn straight forward.. whats the point of using the command when u cant even understand it
So use Windows if you don't like it. Linux is for the more technical user who can work out with just a console and has no need for GUIs.
Some of my customers asking the same question. You can check with command "free -m" and pay attention to buffer/cache value. I would not to worry until your system is starting to use swap
