[Openswan Users] performance ipsec tunnel

[Daniele Melosi]

Good Morning to everyone,

I notice performance decrease of my ipsec tunnel (6.70 Mb/s insteed of 
22 Mb/s without tunnel).

Is there any traffic limits or a solution to improve performance ?

This is my configuration:

         #forwardcontrol=yes
