ARM Freescale i.MX6 Quad @996 MHz, Linux 4.19.100-bsp-yocto-i.mx6-pd20.1.0 (Profile)

Latency plot of system in rack #b, slot #3
Note that this system runs a non-RT kernel.
Data to construct the above plot have been generated using the RT test utility cyclictest.
Command line: cyclictest -l10000000 -m -n -a0 -t1 -p99 -i2000 -h4000 -q
Total number of samples: 10 million
Resolution of latency scale: reduced 
Duration: 5 hours, 33 minutes, lowest P state: performance
Compare latency of primary with shadow system
Characteristics of the 792 highest latencies:
