I cant remember well, and i cant get to my computer, but:
It was an online speed checker, and it said 0.3 MB speed.
is that up or down? It should give you 2 results... download is always higher than up.
If so, sounds like a pretty average upload speed for the UK, i get about .5 mb/s
Who are you with?
0.3mb/s download would be pretty awful though, no way you could for example stream video in real time, even minimum quality youtube. you should really be getting about 2mb/s if you're paying for 10, seems to be how it works.
I had a really awful provider about 2 years ago who gave me less than .3 for download due to excessive throttling at all times, a complete rip off... In fact, no exaggeration, it was most often slower than dialup.
After this i went with O2, who were slow but kicked me off their poor service because i broke their download limits (while no one would tell me exactly what the limits were - a bit like handing out speeding tickets on a road with no speed limit signs and not even the cop will tell you by how much you exceeded the limit.)
I'm currently with another provider who are slightly quicker, but i have the phone with them also and it costs quite a lot per month.
If looking for a new provider i won't make any recommendations other than avoid utilitywarehouse, tiscali and O2, who have all given me a terrible service in the past. BT are also rubbish with pathetic download limitations.
