x86 Intel Core i3-2310E @2100 MHz, Linux 5.10.47-rt46 (Profile)

Latency plot of system in rack #8, slot #2
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 2 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
Compare latency of primary with shadow system
Characteristics of the 100, highest latencies:
