Would it be possible to make a program in KDE and Gnome that works like a ram throule (hack) that works with the system to limit ram caching to the bare mininum and possibly devotes all or most of the ram available to the app/game in focus.

At first this seems like a lot of work but the end results if this can work would be performance astrinomical. There are more and more Linux games being made but most of the new ones aare ram hogs and having ram cached for the background apps acts as a bottle neck for the game and vidio. Video based on a test where I played a game in Gnome and it was realy choppy, I played the same game in XFCE with a much lighter ram load and the game was 100% more playable.

This would go a long way in making Kubuntu and Ubuntu more useable for slower computers and though possibly not the easiest solution to make it would be the eisiest solution for a user to use. I would even go as far as suspending baackground apps to disk like a lap top setup and this may fall into a hole paackage based on a PC version of the laptop sleep with ram throutle instead of cpu scaling.

The end result would result in more usability for older slower machines from the main Kubuntu Ubuntu package.
