Encryption - performance and throughput

[Jon Are Endrerud]

Are there any considerations one should do regarding performace using 3DES and AES128/256 encryption ? Im specially thinking of

througput and cpu load on ASA devices.

Thanx

Hi Jon,

Please look at the throughput for different models when using the 3des/aes encryption.

Also, higher is the encryption level, more is the processing load on the device and hence this should be considered along with overall capability of the device and choose appropriate one according to the requirement.
