Hi,
my guess would be that the file source and UDP sink are much faster than
the UDP source and QT GUI Sink. As UDP is "fire and forget", the
"transmitter" may be pushing more data over the network than the QT GUI
Sink can handle.
To test this, you can replace the QT GUI Sink with a NULL sink, which
just deletes the data. Or you can add a throttle block after the File
Source to reduce the data rate.
Best,
Fabian

why do UDP source and sink not work efficiently in Gnuradio?
I want to use a UDP source and sink in Gnuradio, for a low sample rate
of 10k I see that there is too many packet drop. why network tools does
not work effectively?
can anyone guide you? thanks in advance
*more info:*
I set payload size 1408 I set send null pkt as true or false all state
I had not a good response
see the screenshot and log
