Probably not many, but it's quite possible. I've done 1 Gbps streams off a single box before, it's not much harder to take it out 150ms. Heck for their 60 second test, you could buy some GigE transit ports from someone with a STM64 across the pond and not even pay for it in 95th percentile. :) > Just the fact that you need a ~20 megabyte TCP window size to achieve this > (feel free to correct me if I'm wrong here) seems kind of unusal to me.
