take one point, 4500 uSec from the previous graph and do add a couple of other configurations

Observe the recovery time, which does not include the actual idle state exit latency, just the extra time needed to get to get to adequate CPU frequency, is on average 87 times slower for HWP verses noHWP and 44 times slower the passive/ondemand/noHWP.

Yes, there a few interesting spikes on the passive/ondemand/noHWP graph, but those things we can debug relatively easily (which I will not do).
