Derek: I generally get much faster file downloads than the 75-80kbps you have apparently experienced. For example, the Netscape 14.7 MB Communicator v4.51 file downloaded in under 3 minutes, and that translates into about 80KB/sec or 640 kbps.

In the March issue of PC World, they published some comparative download rates for regular 56 kbps analog modems, ISDN, cable modems, DSL, satellite and T1. They reported that a 1.536 MB compressed .zip file downloaded in 29 seconds with a cable modem and 364 seconds with the standard modem. Those download times translate into about 53 KB/sec or 424 kbps for the cable modem and about 34 kbps for the 56 kbps modem.

So my setup does better than (or at least as well as) the PC World benchmark, but still far short of the 1.5 mbps that Cablevision tells me their system can run at. One of Cablevision's tech guys told me that they currently have three T3 lines feeding about 20,000 subscribers, with zero bottlenecks at their end. He said that the limiting factors in getting up to the full 1.5 mbps rate are a combination of net congestion and the fact that many websites just can't upload stuff that fast.

Seems like eliminating the bottleneck at the subscriber end is only part of the entire picture, and we'll have to wait for the rest of the internet to get up to the same speed.
