what it is you're doing at those rates: I am using a USRP B210 to
transmit and receive pulse signals using attached antennas. The
antennas work at 430MHz. See attached fig.
and what kind of computer/OS you're using:

One thing that struck me--your high-pass filter is very compu-spendy --
with those parameters, there's over 1000 taps.
That's considered rather chunky.
Since it's a decimation=1 filter, it will have to perform over 1000
multiply-accumulate operations and the matching shift
operations on every sample.
That may be what's slowing you down.
