It is unlikely that the RTT will be worse than what they are experiencing now - the size of the pipes mean that the buffers are easily filled with a single TCP connection. But applying the wrong default will have an impact, which could well be noticable.

I agree that real information will be good. We don't really have it, which is why setting a default (based on 2 data points) is not good. The qos-scripts should be tailored to each user.
