Geode(TM) Integrated Processor by AMD PCS, Linux 4.9.47-rt37-geode (Profile)

Latency plot of system in rack #4, slot #3
Data to construct the above plot have been generated using the RT test utility cyclictest.
Command line: cyclictest -l100000000 -m -n -a0 -t1 -p99 -i200 -h400 -q
Total number of samples: 100 million
Resolution of latency scale: normal
Duration: 5 hours, 33 minutes
Compare latency of primary with shadow system
Characteristics of the highest latencies:
