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.

Total number of samples: 50.5 million
Resolution of latency scale: normal
Duration: 5 hours, 33 minutes, lowest P state: performance
