I have worked on server room networking, and found that it takes quite a
bit of tweaking of the interfaces and the TCP stack to get things up to
80 percent usage of a gigabit link. Both ends. So your side can go
like the wind, but your data source may not be able to fill the pipe.
So I agree that, for most people, this will be pure marketing hype.
As for the 4400 users, that's the classical oversubscription model.
