Nicht zwingend:
System load averages is the average number of processes that are either
in a runnable or uninterruptable state. A process in a runnable state
is either using the CPU or waiting to use the CPU. A process in unin-
terruptable state is waiting for some I/O access, eg waiting for disk.
The averages are taken over the three time intervals. Load averages
are not normalized for the number of CPUs in a system, so a load aver-
age of 1 means a single CPU system is loaded all the time while on a 4
CPU system it means it was idle 75% of the time.
