Default latency plot of system in rack #e, slot #2

x86 Intel Core i5-8365UE @1600 MHz, Linux 5.19.0-rc7-rt7 (Profile)

Latency plot of system in rack #e, slot #2

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 -Sp90 -i200 -h400 -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 100 highest latencies:
