To Reduce CPU Usage by Turning Off Display of Icons in Menus

Some items in menus display an icon beside the item. To turn off this feature, run the following command:

# gconftool-2 --type bool --set /desktop/gnome/interface/menus_have_icons false

Alternatively, users can choose Applications -> Desktop Preferences -> Menus & Toolbars, then deselect the Show icons in menus option.
