x86 Intel Celeron G1620 @2700 MHz, Linux 5.10.35-rt39 (Profile)

Latency plot of system in rack #8, slot #7
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: ondemand
Compare latency of primary with shadow system
Characteristics of all highest latencies:
