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 CC150/160 appliances). For example, 
 shows a system that consistently swaps memory in high volumes. To 
improve performance, you may need to add IronPort appliances to your network 
or tune your configuration to ensure maximum throughput.
