I am interested to know the WAN Throughput Performance of Cisco 2900 / 3900 G2 Routers.
From some cisco offical documentation, it had mentioned the below figures:
The G2 platforms accommodate the following throughput:
• 1941/2910 - up to 25Mbps
• 2911 - up to 35Mbps
• 2921 - up to 50Mbps
• 2951 - up to 75Mbps
• 3925 - up to 100Mbps
• 3945 – up to 150Mbps
But did not mention the above figures are average throughput or maximum throughput.
On other hand, there did not exist any throughput figure for WAN throghput if traffic will be under encryption.
There existed another discussion on https://supportforums.cisco.com/thread/344391?tstart=0 with information as:
"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."
How 848Mbps is much larger than 150Mbps for 3945?
I am interested on souring some routers on WAN connection with or without IPSec encryption under normal traffic (e.g. IMIX) rather than short or long packets.
