How efficient is DSL vs. dialup?

How efficient is DSL vs. dialup?

DSL is certainly much faster than a standard dialup connection. While the dialup connection will give you a maximum of 52 Kbps downstream , DSL starts from 128 Kbps and can go up to 2048 Kbps!

In practice the above figures translate to around 5 Kb/sec for dialup and for DSL it varies depending on your connection speed. We have a 386 Kbps here in the office and I average around 25-30 Kb/sec sustained downloads with peaks up to 45 Kb/sec.

Apart from the faster speeds DSL provides, it is also a permanent connection. This means no waiting for your modem to pick up the line and dial to your Internet provider. The connection is permanently online and ready to use.
