The following link shows how to install and configure the AIM in a 2600 router:

From experience, using IPSEC on a 2 Mbps point to point link with a 3620 without a VPN accelerator will max out the processor when sending data across the line, you should be able to prove this by looking at the cpu processes on your router (as you have allready noticed) when sending data across the line

I think the specific process to look out for is called "encryption" but can't quite rember, if you enter "show proc cpu | e 0.00", this will display all processes that are using resources and you should see the offending process with a high % of processor utilisation.
