System Capacity – Outgoing Mail
System Capacity – System Load
The system load report shows the overall CPU usage on the Email Security appliances. 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 an 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.
