Okay, I have to say that using ADSL Guide speed test since going on Sky Broadband has given me some weird results in the same range as you mention, I suspect this is a MAC thing. For a web speed test site try these links:
Sky User - Broadband Speed Tester
Namesco BroadbandMax ADSL Broadband Bandwidth speedtest | Test your ADSL Broadband connection speed
BT Openworld
A more reliable measure would be doing an FTP download client test, if you haven't got an FTP client program download Transmit demo version via this link:
Panic - Transmit 3 - The next-generation Mac OS X FTP client!
Then log into this FTP site via Transmit:
ftp.mirror.ac.uk
Then copy and paste this initial path:
sites/ftp.freebsd.org/ftp/pub/FreeBSD/releases/amd64/ISO-IMAGES/6.1/
Now drag onto your desktop the file out of Transmit called:
6.1-RELEASE-amd64-bootonly.iso
See what KB/s download rate you are getting.
Hopefully using these instructions you might get some confirmation of your actual download/upload speeds.
