Well I suspect the bandedge fll in the bpsk chains takes up a little too
much juice. I might suggest experimenting with the gmsk chains.

Anyway, this is expected. benchmark is an example of implementing a mac
layer w/ gnuradio in python. But its not going to yield continuous
high-rate throughput.

When you code up your application, I suggest making heavy use of the
neon SIMD. :-)
