  Note that the speed between your machine and any remote site is going to
be the minimum of the available bandwidths on all of the links between the
two.
  On dial-up, that's almost always the connection between your phone and the
ISP's modem.  Occasionally, it's the link between the destination web site
and their ISP.

  The other links in the chain tend to have much higher TOTAL bandwidth,
which your traffic is sharing with everyone else who is trying to pass
traffic across that link.  So at any given moment, the bottleneck *could* be
a problem where one ISP hands traffic off to another, or within a given
ISP's backbone network.
  You can get a rough idea of the path from you to a website using
traceroute (which Windows spells "tracert").  Note that return traffic from
the web site to you may follow a slightly different path.

  You can't really guarantee that traffic conditions on the net are going to
be the same from one test to the next.  You probably need to take three
measurements or more, at different times of day, and average them.
  Even then, a slowdown might not be your link, and might not be due to
traffic -- it could still be due to a problem out in the Internet somewhere.
