For example, for a 1K and 1M FFTs (measuring MFLOP/s on a ~3.6 GHz
Xeon):


Updating this with the PATIENT 1M performance:

	ESTIMATE        MEASURE         PATIENT
        (times == 1)    (times == 15)   (times == 0)
1K      4959            6355            7482
32K     3985            5370            6488
1M       687            1735            3177
