In the EM, we can view the CPU usage at the server(OS) level that the CPU
I/O wait is very high.
And from the database level, statspack will tell use the time about IO, such
as scatter read or sequential read. Is the time spent on scatter/sequential
read in the eye of oracle is the same or at least related to the "CPU I/O
wait' at the unix level?
