Data to construct the above plot have been generated using the RT test utility cyclictest.
Unexpectedly long latencies may be caused by a total of 26524 SMIs that occured during the measurement.
Total number of samples: 100 million
Resolution of latency scale: normal
Duration: 5 hours, 33 minutes, lowest P state: performance
Characteristics of the 792 highest latencies:
