Implementing traffic shaping on a client end can help somewhat..

It can at least mean that two tcp connections can each go at half
speed...

And using smaller window sizes, can help alleviate the problem somewhat,
too..

But gaming that relys on low latency is pretty much out still. The
bandwidth's just too small to share realistically...

But as far as normal traffic goes, I think the situation is better now
than it was in the previous situation; as intelligent shaping is useful. :)

And it's pretty damn rude to go dropping as many packets, as the old
situation used to, wasting the sending end's bandwidth.

Paradise cable does a much better job of shaping though..

Here's wishing for more than 128kbit bandwidth with semi-reasonable
bandwidth caps.

Oh, and I'm guessing that if/when that extra 36 msec latency add-on gets
removed then that could make gaming slightly better with simultaneous tcp
connections and client-end shaping at the same time......

Ben.
