CPU usage can *NEVER* exceed 100% ... but load average can go to any
level... so if you have 2 programs that normally hog the CPU and usage is
100% when run singularly... then if run them both together(simultaneously)
they would need 200% cpu usage... but the OS shares the CPU cycles between
the processes and so both of them run.. but they will be running at half
speed.. so the load average would be 2.0 ... but the processor usage would
remain 100%.
in other words if load average goes over 1.0 all your tasks will run
slower as they will get lesser cpu cycles assigned to them.
