Problem with flowgraph

Hello,
I am working on a small application which is supposed to receive/send
data packets(i have two usrp nodes) and sense spectrum for any energy
that may be present.

I am using benchmark_rx/tx.py for the same. I have modified the
receive_path.py in order to accomodate the spectrum sensing ability
(have used code bits from usrp_spectrum_sense.py) . Hence ,on the
receive side, I have a couple of flow graphs branching out of the usrp
source instance.

I am able to sense the spectrum appropriately but the problem is that
the data packet transfer between the nodes is deteriorating
significantly.
Further, if I comment out the spectrum sense branch, the data packets
are exchanged very well.
Can somebody help me figure out why this is happening.

Thank you

Are you getting an uU’s or uO’s? If so, you’re running out of CPU
cycles.
