I’m having an odd issue where SAR is reporting wildly
different stats than what the system is doing.


Â*


I’m not sure where sa is pulling it’s numbers
from but I definitely don’t and haven’t had the CPUs running 36% for
users and 63% for system for a long time.Â* It’s more likely the
system had been idle.


Â*


Any ideas?
