Here is a site that ran actual throughput tests: You can see that the pkzip is much more effective than any modem compression, and the difference in the results between the pkzip and V. What is the difference between cloud computing and virtualization? With some phone systems and the distance to the central office, you may not be able to get 56k.

Since the second and subsequent calls would not need to make those calculations, subsequent connection times will usually be shorter. Here are the standard DTE speeds.
