System Idle Process

[Ragidy_man]

Does anyone know what it is/does?

is it important?

and is it suppose to take up 45-70 cpu and only 28k mem usage

(ctrl+alt+del processes)

Not sure what it does but yes it is supposed to take up around 50 cpu.

The CPU must be doing something all the time, even when there are no active processes. So most OS's have an idle process, all it does is track how much CPU time is being used. All the idle process is, is a loop of HALT instructions which basically halts the CPU until the next interrupt.

So basically you have nothing to worry about. If it says its using 99 CPU, then it really is, cause you have no other active processes running. It's just something to do when you're not running anything.
