You are seeing the stats for the session from the begining of time for the session. This command is useful because it shows at a glance the overall CPU statistics and the processes consuming the most CPU (ranked in descending order of CPU usage). Source

You are changing the mathematical model that spits out the cost of a given plan. make sure you are using the CBO currently. So, there are 300 connections in the PROD1 database coming from the DB1 database through database links.
Similarly, knowing only the run queue will not provide you with knowledge on the exact CPU usage, nor the spread of time usage across system and user modes. easy to expand, easy to reconfigure, easy to manage -- all in a big cabinet. However, if us + sy time on a multiuser system exceeds 80 percent, the processes may spend time waiting in the run queue.

Here is scenario: The server is slow, let us find which sql are culprit. have a peek here Hence, 100% CPU utilization may not be sub-optimal because 100% CPU simply means that all the processors are busy (that's how the server SMP architecture is designed).
