VIA QuadCore L4700 @ 1.2+ GHz, Linux 3.18.43-rt46 (Profile)

Latency plot of system in rack #b, slot #4
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
Characteristics of the 20 highest latencies:
