New It's helpful to remember just what "load average" means.
Someone told me it was how many scheduled items in the kernel missed their turn in the schedule. Sounds like one of the few times that "load average" is actually highly misleading.

New yea, That is a good analogy...
But I have always described it, Job waiting in Queue during the sample frequency.

Or in other words, Jobs waiting for their turn in the scheduling.

Sort of like Left turn lanes in the USA (Right turn lanes in places that drive on the wrong side of the road).

At busy intersections, left turn lanes typically build up a queue of cars to turn left. Most of the time only 3-5 get through per light. Sometimes takes 5 or 6 light cycles to get through it.
