Default latency plot of system in rack #0, slot #5

Click here to display the system's profile data or here to proceed to next system.

Click on a legend element to toggle display of that core, ctrl-click inverts display, shift-click enables all.
Data to construct the above plot have been generated using the RT test utility cyclictest.
Unexpectedly long latencies may be caused by SMIs
Total number of samples: 100 million
Resolution of latency scale: normal
Duration: 5 hours, 33 minutes, lowest P state: performance
Compare latency of primary with shadow system

Characteristics of the 100 highest latencies:
