## Symptoms

- * When enabling Mobile Access in the Appliance Sizing Tool, the generated report shows a message:  
  "`The sizing of Mobile Access Blade is optimized for portal Scenario. Read Security Knowledge sk96450 for advanced mobile blade sizing with SSL Network Extender (SNX)`".  

* When using SSL Network Extender (SNX), utilization of one of the CPU cores is high.  

* When using SNX Application Mode, user connections are dropped.

## Cause

1. SSL data encryption and decryption is handled on one CPU core. The Appliance Sizing Tool assumes processing scalability of multiple CPU cores and therefore may produce an incorrect recommendation.
2. When using SNX Application Mode, there is a limit of 500 concurrent connections.
