Paralyzed, try rebooting your router / firewall (I really hope you have one!) and your cable modem. Some brands have issues that cause performance to degrade over time.
It depends on the time of day though- this was done at ~5:40pm in the UK, but after most people have gone to bed, it gets alot quicker due tio less traffic- typically about 7-8mb/s. Still crap compared to some of you bastards- I hate you and your super fast internet connections...
Edit:
20 minutes later and its nearly twice as fast- bizarre......
Damn Art1k, thats a bit fast isnt it? I would run an extension cable from your work to your home- have a few inline hubs/boosters whatever to compensate for the voltage drop (unless its fibre optic), and it would still be faster than most other peoples internet...
