Latency plot of system in rack #b, slot #5
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, lowest P state: ondemand
The worst-case latency is about 1.57 times higher under extreme CPU load.
Results of all systems under extreme CPU load are combined on this summary graph.
Characteristics of the highest latencies:
