ARM Freescale i.MX535 @1000 MHz, Linux 4.19.142-rt63+ (Profile)

Latency plot of shadow in rack #4, slot #6
Data to construct the above plot have been generated using the RT test utility cyclictest.
Command line: cyclictest -l50000000 -m -n -a0 -t1 -p99 -h400 -i400 -q
Total number of samples: 50 million
Resolution of latency scale: normal
Duration: 5 hours, 33 minutes
Compare latency of primary with shadow system
Characteristics of the 376 highest latencies:
