Intel(R) Core(TM) i9-9900K CPU @ 3.60GHz, Linux 5.10.21-rt34 (Profile)

Latency plot of system in rack #0, slot #8
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 -Up99 -i200 -h400 -q done
Total number of samples: 100 million
Resolution of latency scale: normal
Duration: 5 hours, 33 minutes, lowest P state: performance
Compare latency of primary with shadow system
Characteristics of the 100 highest latencies:
