ARMv7 Processor rev 2 (v7l), Linux 4.1.18-rt17-g4415f52 (Profile)

Latency plot of system in rack #a, slot #5
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
Compare latency of primary with shadow system
The worst-case latency is NOT higher under extreme CPU load.
Results of all systems under extreme CPU load are combined on this summary graph.
