I had overlooked that this could be a single CPU system.
For such a test the potential limiting factors can be either 
of:

        1. storage.
        2. the single cp thread burning a CPU.
        3. total system CPU overload.

You've already indicated that storage is not 100% busy.
The cp(1) thread is not burning a CPU.
And it looks like the system is not CPU saturated, right ?

I'd  argue that the conjunction   of those 3 things somewhat
points to 'a problem'.
