Two, adjust the application priority The application range of priority values from -20 to 19, the smaller the number of higher priority. In general, the general application priority (CPU weight) is 0, if the priority for common procedures has a high natural, starting and running speed will be faster. We can use the command nice -n program name (the value of N from -20 to 19) to adjust the priority of application, the need to pay attention to is the ordinary user can adjust the application of between 0 to 19 of the priority value, only root has the right to adjust the higher priority values (from -20 to 19). Three, the use of low load desktop environment or window manager KDE is the Linux desktop in the most perfect, but most of the desktop environment, XFce4, FVWM, IceWM, Window Maker this kind of desktop environment and window manager. Although the function KDE not perfect, but the running speed is much faster than the KDE, it can be said that the use of low load desktop environment and the window manager is used and the speed of exchange function. Here I recommend using the XFce4 desktop environment.
