x86 VIA Samuel 2 @533 MHz, Linux 3.18.9-rt4 (Profile)

Latency plot of system in rack #3, slot #7
Data to construct the above plot have been generated using the RT test utility cyclictest.
Command line: cyclictest -l100000000 -m -n -a0 -t1 -p98 -i200 -h1000 -q
Total number of samples: 100 million
Resolution of latency scale: reduced 
Duration: 5 hours, 33 minutes, lowest P state: performance
Characteristics of the 376 highest latencies:
