I ran the test at the site you used on mine it read 6508kbps which is 813KB/s and 356kbps which is 44.5 KB/s.
kbps means
kilobit and KB/s means
kilobyte it takes 8kbps to make 1KB/s

So the results you got mean you have about 33KB/s Download and 7KB/s Upload. Use the speed test site at the link below it is in the Czech Republic, it is located in Prague. And should be more accurate for you. It showed me as 159KB/s Download which would be about right for 1/2 way around the world. I think the test site you used is in the US.
