Here's the results of my test to speedtest.net. (Bigpond Cable)
I ran the test several times and got wildly varying results from 8000kbps to 30000kbps.
It seems to depend which test server the application connects to.
Try going to
Whirlpool for a discussion of broadband speeds etc. There are also some links to other local speed tests.
I did a comparison recently to see if I could get reasonable speeds with ADSL. Even though my local exchange does have ADSL2+ capabilities, at 5 Kms from the exchange, the best speed I could hope for was <8000kbps.
