To all:
Here is an excellent summary of all the factors involved in how fast a
file is downloaded to your computer:
* the power of your work station (computer) and software (browser)
configuration
* the (nominal) speed of your connection to your ISP (Internet
service provider)
* the Internet traffic between your ISP and the ISP for the site you
are accessing
* the speed of the connection between the "other" ISP and your
target site
* the power of the server hosting the pages or files you are
interested in
*The weakest link in this chain determines the final result
*The above is from a discussion that, while 10 years old by Manfred
Kuechler at Hunter College, CUNY, still summarizes the problems in an
excellent manner.
