Latency plot of system in rack #1, slot #5
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 -l100000000 -m -Sp99 -i200 -h400 -q
Total number of samples: 100 million
Resolution of latency scale: normal
Duration: 5 hours, 33 minutes
Characteristics of the 20 highest latencies:
