wrong, you'll get 1% of the connections instead of 0.1%. So you'll be
more responsible for the saturation of some active equipments which
are sensible to connections, but this has nothing to do with the
bandwidth, nor the link.

It may be usefull only if you have a very high latency and a small
TCP window, I think.

Cheers,
