x86 Intel Pentium @133 MHz, Linux 4.18.7-rt5 (Profile)

Latency plot of system in rack #3, slot #5
Data to construct the above plot have been generated using the RT test utility cyclictest.
Command line: cyclictest -l25000000 -m -n -a0 -t1 -p99 -i800 -h1000 -q
Total number of samples: 25 million
Resolution of latency scale: reduced 
Duration: 5 hours, 33 minutes
Compare latency of primary with shadow system
Characteristics of all highest latencies:
