Intel(R) Core(TM) i3-8145UE CPU @ 2.20GHz, Linux 4.19.152-rt64 (Profile)

Latency plot of system in rack #e, slot #6
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 -n -p90 -i200 -h400 -a0-2 -t3 -q done
Total number of samples: 100 million
Resolution of latency scale: normal
Duration: 5 hours, 33 minutes, lowest P state: performance
Characteristics of the 50 highest latencies:
