Default Performance reporting issues.

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


*


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.* It’s more likely the
system had been idle.


*


Any ideas?
