Latency created by VPN encryption

Can anyone tell me more or less how much "latency" a VPN IPSEC with DES encrytion adds to your WAN links, as opposed to no VPN encryption.I am experiencing high extended ping rtt's of 2000MS on some of my links that are running VPN IPSEC end to end.


Re: Latency created by VPN encryption

Often times complex troubleshooting issues are best addressed in an interactive trouble-shooting session with one of our trained technical assistance engineers. While other forum users may be able to help, it’s often difficult to do so for this type of issue.

To utilize the resources at our Technical Assistance Center, please visit and to open a case with one of our TAC engineers, visit

If anyone else in the forum has some advice, please reply to this thread.

Thank you for posting.
