Re: [Discuss-gnuradio] Speed test went wrong.

[West, Nathan]

I'm not familiar with that exact flowgraph, but nothing will "break down" in a CPU only flowgraph. Drag the ctrl port perf monitor block on to the flowgraph and look for the avg throughput counter for a block you care about. It'll give you items/sec. PS - the throttle block only gives you an approximate amount of throughput. The actual rate has nothing to do with whether the flowgraph works/breaks.

Dear all,
 I wondered what would be the maximum sample rate that my PC can handle for
a basic psk mod-demod. I have used the “prbs_test.grc” from gr-mapper as it
contains all the necessary blocks. I changed the sample rate for the
throttle to 32k, 320k,10M, 100M even 10G but the system did not break down.
I repeated the experiment using different examples but the result was the
same.
What went wrong and do you know any appropriate projects for speed
measurements.
