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.
top - 00:52:37 up 13:46, 1 user, load average: 2.00, 2.30, 2.43
