Intel(R) Celeron(R) CPU N3350 @ 1.10GHz, Linux 4.18.7-rt5 (Profile)

Latency plot of system in rack #c, slot #4
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 -q
Total number of samples: 100 million
Resolution of latency scale: normal
Duration: 5 hours, 33 minutes, lowest P state: performance
The worst-case latency is about 1.10 times higher under extreme CPU load.
Results of all systems under extreme CPU load are combined on this summary graph.
The worst-case latency is about 1.19 times higher under graphics load.
Results of all systems with accelerated graphics are combined on this summary graph.
Characteristics of the highest latencies:
