the narration of the graph would be like this:
On the HTonTurboOn test case.. the x axis 14 saturated CPUs has y axis
value of about 100,000 LIOs/Elap which means on the workload level
the LIOs/sec
range is about 14 x 100,000 = 1400000 but at this point I'm consuming part
of my response time on CPU wait (run queue) for 1.2secs per execution (from
2.76 total elapsed.. not shown on graph)
