And how much you get for 0?  I'm asking because the only thing I can
think of is that the network you are using has the fastest speed of
10Mib and since the lowest number (1) for the SetSpeed function means
1MiB which is 8Mib, it might just not go way higher...

Sorry if I missed something and this question is irrelevant.
