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. The calculations themselves take less than 20 milliseconds.

So phase 1 should take about 3 round trips.
