In theory Cable carriers local loops carry ~20Mbs or so, but that is to
be shared by all, so they cap you at the lower amounts so that everybody
gets something. In Raleigh where I live, Timer Warner does a decent job
of not oversubscribing the local loops (surprising since I live near the
NC State campus) and I almost always got 3.5Mbps downstream. Now if I
could only get them to give me better than 40K/sec upstream, life would
be perfect.
