In general with ADSL your ISP sets the link speed lower than your modem is
capable of. I forget what the max rate on ADSL-1 (as currently used by BT)
is, but for example until recently I had a 512K connection, now its 2Megs.
However in addition there is "contention". That is if you have 5 to 1
contention, the PIPE between the Exchange and the ISP will only have 2 Megs
of bandwidth for every 5 customers. So if there are 10 x 2Meg customers
there will be a 4 meg pipe to the ISP.

In addition we are the stage now where there may be contention at the other
end. If a server has a 100 meg card, and 100 users try and access it, they
are not going to get 2 Meg each...
