Load avg is the number of processes in the running queue, which can be
either waiting to be run or actually running.
So if you had 100% CPU usage, then you'd most definitely have a load
avg of 64, which is neither good or bad. It may simply mean that
you're using your hardware's full potential.
If your processes are waiting but not using CPU or I/O time... all I
can think of is mcelog (it's the only application I've ever witnessed
doing that). Do check ps/top and try to find out which processes are
in a waiting state to have a little more insight.
