x86 Intel Celeron N3350 @1100 MHz, Linux 5.15.32-rt39 (Profile)

Latency plot of system in rack #6, slot #4
Data to construct the above plot have been generated using the RT test utility cyclictest.
Unexpectedly long latencies may be caused by a total of 26416 SMIs that occured during the measurement.
Command line: cyclictest -l100000000 -m -Sp99 -i200 -h400 --smi -q
Total number of samples: 100 million
Resolution of latency scale: normal
Duration: 5 hours, 33 minutes, lowest P state: performance
Characteristics of the 100, Linux 4.9.20-rt16, x86_64 highest latencies:
