Default latency plot of system in rack #0, slot #0

x86 Intel Core i3-2100T @2500 MHz, Linux 4.14.28-rt23 (Profile)

Latency plot of system in rack #0, slot #0

Data to construct the above plot have been generated using the RT test utility cyclictest.
Unexpectedly long latencies may be caused by SMIs
Command line: cyclictest -l100000000 -m -Sp99 -i200 -h400 --smi -q
Total number of samples: 100 million
Resolution of latency scale: normal
Duration: 5 hours, 33 minutes, lowest P state: performance

Characteristics of the 100 highest latencies:
