Additionally it will depend on the round trip time across the network between the two peers. Vendors who are selling network boxes that can do a large number of simultaneous IKE negotiations tend to care more about simultaneous IKE SA negotiations per second than they do the actual negotiation tim

What Dan and Gregory said. But assuming an unloaded gateway, with "normal" hardware (Any Intel, AMD or PowerPC processor from the last 10 years or a recent ARM), then even if you use relatively secure parameters (2048-bit DH group, 2048-bit RSA keys) the round trip time is going to dominate. Th
