Latency plot of system in rack #1, slot #5
Note that this system runs a non-RT kernel.
Data to construct the above plot have been generated using the RT test utility cyclictest.
Command line: cyclictest -l10000000 -m -Sp99 -i2000 -h3000 -q
Total number of samples: 10 million
Resolution of latency scale: reduced 
Duration: 5 hours, 33 minutes, lowest P state: performance
Characteristics of the 50 highest latencies:
