ARM Freescale i.MX6UL @528 MHz, Linux 4.18.7-rt5 (Profile)

Latency plot of shadow in rack #5, slot #7
Data to construct the above plot have been generated using the RT test utility cyclictest.
Command line: cyclictest -l50500000 -m -n -a0 -t1 -p99 -i396 -h400 -q
Total number of samples: 50.5 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 376 highest latencies:
