x86 Intel Atom x6425RE @1900 MHz, Linux 5.17.0-rt15 (Profile)

Latency plot of system in rack #e, slot #4
Data to construct the above plot have been generated using the RT test utility cyclictest.
Command line: cyclictest -l100000000 -m -Sp99 -i200 -h400 -q done
Total number of samples: 100 million
Resolution of latency scale: normal
Duration: 5 hours, 33 minutes, lowest P state: performance
