What's the difference between load average and CPU load?

Here's the output of top:




top - 23:30:49 up 2:18, 1 user, load average: 4.36, 4.36, 4.39
Tasks: 105 total, 2 running, 103 sleeping, 0 stopped, 0 zombie
Cpu(s): 3.6%us, 8.0%sy, 0.0%ni, 73.4%id, 9.0%wa, 1.1%hi, 4.9%si, 0.0%st
Mem: 2029820k total, 1979312k used, 50508k free, 6828k buffers

Swap: 5947384k total, 0k used, 5947384k free, 1855304k cached


How can the load average be high while the CPU load is low.



How is load average calculated?
