Are you using 3DES encryption at the IOS level ??
This could be causing most of the impact ... you can add SEP cards to do
the 3DES encryption at the hardware level , but I don't know if 2621
supports SEP.

The router model is 2621 on both sides with IOS version 11.3 and there is
only one tunnel configured.. The average CPU utilization is around 41%..

what is the router involved? model numbers, RAM, IOS version?
have you checked CPU usage? single or multiple tunnels?

Subject: Perfomance prob with Router-Router IPSEC tunnel..
Hi Guyz,
We are having a cisco router-router IPSEC tunnel between two
locations(Intranet VPN) over an internal leased line.The performance is very
poor even though the link is only 40% utilised. On examining we found that
the tunnel bandwidth is only 9k..Is there anyway I can increase the tunnel
bandwidth or can i have an IPSEC connection without using a tunnel so that i
can use more bandwidth in the link.. There is a bandwidth command in the
interface mode but it is only for calculation of cost and it has no impact
on the actual tunnel bandwidth
Can anyone pls help me out with this...Thanx in advance..
Regards,
Nandu
