Click here to display the system's profile data.
Click on a legend element to toggle display of that core, ctrl-click inverts display, shift-click enables all.

Note that at least one system runs a non-RT kernel (x scale expanded to 2000 µs).
Data to construct the above plot have been generated using the RT test utility cyclictest.
Unexpectedly long latencies may be caused by SMIs
