Check for processes in the uninterruptible sleep mode (D in ps). Those
processes contribute a full point to your load average, for each process in
wait. That is, if you have 15 processes in the D state, your load average
will be 15. This state is normally caused by a slow i/o process. There's
nothing you can do about it, unless you know which i/o is slow, and can
speed it up.
