How can this 'top' command output make sense? Load over 7 and total CPU use ~5%

I think Wojciech means '...which is NOT measure of CPU _utilization_'

In that case he's correct: whenever the CPU has to wait a lot for I/O,
like network and disk, then the _load_ will go up, while the CPU
_utilization_ stays low.
