Comment: cpu frequency corrected on daq-xpp-cam02.

...

All daq nodes should run the cpu frequency governor in "performance" mode.

As of this writing (May 2, 2022) the daq node daq-xpp-cam02 is not running the cpu frequency governor in "performance" mode.
It appears to be running in "ondemand" mode, which  "tries to use the slowest speed as much as possible, but quickly switches up or down when needed."
