improve message throughput. High CPU usage may not indicate a system capacity
problem. The CPU Usage by Function graph that displays the percentage of CPU
cycles used by different functions, such as the Web Proxy and Logging. The CPU
Usage by Function graph can indicate which appliance components use the most
resources. If you need to optimize your appliance, this graph can help you
determine which functions may need to be tuned.
