Intel(R) Core(TM)2 Quad CPU @ 2.40GHz, Linux 3.2.46-rt67-32 (Profile)

Latency plot of system in rack #3, slot #1
Data to construct the above plot have been generated using the RT test utility cyclictest.
Command line: cyclictest -l100000000 -m -Sp99 -i200 -h400 -q
Total number of samples: 100 million
Resolution of latency scale: normal
Duration: 5 hours, 33 minutes, lowest P state: performance
Characteristics of the 20 highest latencies:
