I wanted to ask if any of you have real world numbers on the GETVPN performance with 2911 routers?
I have a pretty simple setup with 2 key servers - 4 group members. I connected 2 laptops on two different group members and did an iperf test. Unfortunately the results were pretty disheartening. I only got 66-67Mbps/sec max and the router CPU was constantly at 77% !!
All the routers were 2911 with 2gigs of RAM installed and I was using AES 256 for the traffic. (I don't think lowering to 128 bits would give me that much of a performance boost). I wish we could afford ASRs but we can't so I would love to hear other people's experience on this with real world results with similar platforms.
