HI all,
Why 3945 throughput for encrypted traffic (848Mbps) is much larger than its normal throughput for 150Mbps?

From Cisco's support forums: "With IPSEC/AES we can do 848Mbps on a 3945 and 1400byte packets and the 2900s range from 150-280Mbps or so depending on which 2900." https://supportforums.cisco.com/thread/344391?tstart=0 Anyone has more data on this? Thanks!

Should we count half of above figures for IPSec tunnels? For example, two 3945 routers could only provide average (or maximum) 150/2 = 75Mbps encrypted traffic in between.
