I remember it may be possible to change Windows XP from "being a desktop mode" to more suited for being a server in a "server mode" -- probably more RAM allocated for hard disk caching, network resources, etc, instead of for GUI resource.

On Windows 7, is that possible through control panel too?

Do you mean the Perfomance Options where you can choose between Adjust Best Performance for Programs or Background Services? They're still there, in the same place. Right click the Computer icon, Properties, Advanced System Settings, Advanced, select the Performance Settings, open Advanced tab

not sure if they are the same... server is more server related... background services can be anything... weather checking... CPU meter... – 太極者無極而生 Mar 1 '11 at 10:51
According to the context help, this merely switches the scheduler between prioritizing the foreground program ("Programs") and giving equal CPU share to foreground and background ("Background services"). However, the system cache option is in the same place, labelled Memory usage, and this seems like what @Jian was looking for. – grawity Mar 1 '11 at 13:25

You can find a guide on optimizing Windows 7 for performance including disabling visual effects, disabling startup programs, and defragmenting your hard drive here on You can also find articles on monitoring and maintaining system performance here at the Springboard site on TechNet.
