Those numbers are the interrupts generated, if you check that file often enough you will be able to see who is causing more interrupts. Maybe doing something like this is useful: $ watch cat /proc/interrupts And just watch the numbers grow, you might find your culprit there. For example, i8042 is the driver that controls your mouse and keyboard (note that there are two i8042 in the list). If you move the mouse constantly you will see one of them interrupting the CPU, but if you type constantly on your keyboard you will see the other one moving up. Equally, if you start to receive packets through the network card you will see eth0 generating more interrupts. Cheers, -William ¡Todo sobre Amor y Sexo!
