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.
