you sure you looked right? in the speed test, it will show your result in Kbps, and in downloads,most likely it will show it in kB/s. the only big difference here is the letter "b". Kb means kilobits, kB means kilobytes. 1 byte == 8 bits.
in your case, your speed test tells us that your connection speed is 73 Kbps. following the given information above, 73 Kbps is almost equal to 9 kB/s.
with that out of the way, please tell us your isp, and what plan you have. have you tweaked you connection settings?
