x86 AMD G-T48L @1400 MHz, Linux 4.4.4-rt11 (Profile)

Latency plot of system in rack #c, slot #3
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
Compare latency of primary with shadow system
Characteristics of the 792 highest latencies:
