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
Compare latency of primary with shadow system
