Note about Memory Page Swapping
The system is designed to swap memory regularly, so some memory swapping is 
expected and is not an indication of problems with your appliance. Unless the 
system consistently swaps memory in high volumes, memory swapping is normal 
and expected behavior (especially on C150/C160 appliances). For example, 
 shows a system that consistently swaps memory in high volumes. To 
improve performance, you may need to add Cisco IronPort appliances to your 
network or tune your configuration to ensure maximum throughput.
