so your statement " The below is occupying 99% of CPU yet overall we have
84.5% idle CPU." is accurate.
This line: " %Cpu(s): 12.5 us, 2.8 sy, 0.0 ni, 84.5 id, 0.0 wa, 0.0
hi, 0.1 si, 0.0 st" is an aggregate function.

Hmmm....when running top, and you press the "1" key on your keyboard,
does it show cpu0 --> cpu7 ?
Just a guess....I can't imagine a system with a 52 Gb sga being only 1
vCPU...

Hi All,
Can someone explain the meaning of IRIX mode for top command in Linux?
For databases running on VM's, when running top, should we turn off the
IRIX mode to get the exact CPU utilization? The below is occupying 99% of
CPU yet overall we have 84.5% idle CPU.
