btw, from proc(5) for Linux:

user   (1) Time spent in user mode.

nice   (2) Time spent in user mode with low priority (nice).

system (3) Time spent in system mode.

idle   (4) Time spent in the idle task.  This value should be USER_HZ times the second entry in the /proc/uptime pseudo-file.

iowait (since Linux 2.5.41)
      (5) Time waiting for I/O to complete.

irq (since Linux 2.6.0-test4)
      (6) Time servicing interrupts.

softirq (since Linux 2.6.0-test4)
      (7) Time servicing softirqs.
