System Capacity-System Load
The system load report shows the overall CPU usage on your appliance. AsyncOS is optimized to use
idle CPU resources to improve message throughput. High CPU usage may not indicate a system capacity
problem. If the high CPU usage is coupled with consistent, high-volume memory page swapping, you
may have a capacity problem. This page also shows a graph that displays the amount of CPU used by
different functions, including mail processing, spam and virus engines, reporting, and quarantines. The
CPU-by-function graph is a good indicator of which areas of the product use the most resources on your
system. If you need to optimize your appliance, this graph can help you determine which functions may
need to be tuned or disabled.

The memory page swapping graph shows how frequently the system must page to disk.
