At least in most of my real world experience, they don’t tend to diverge all that much. Further, post-initiation performance seems to be largely on par v4<->v6 and without NAT, I see faster v4 connection startup times. V6 appears to still have a slight advantage, but it’s more like 5-10% than 30%. Owen
