Per the datasheet below Cisco states that you can up to 750 VPNs configured on an ASA 5520 with 225Mb/s throughput. What throughput can you expect as you add VPNs on the outside interface? Would it be 225Mb/s divided by the number of VPNs you put on that outside interface or can you get 225Mb/s sustained for each VPN?
