Hi,
I have a signal processing block that includes a zero-padded FFT (50%
zeros) that I built for the N310. Because of the throttling that occurs
during insertion of zeros, I expect that my FFT will need to be clocked at
a bit more than twice the max sample rate. So, since I want to operate the

basically be the exact same as what benchmark_rate is running, and yet

Thanks for your answer.
I tried to use benchmark_rate, and I don’t have any sample loss at
200MS/s.
On GnuRadio with a very simple flowgraph (USRP Source -> Null Sink) I
still have very regular (every few seconds) overflows.
In both cases,
Thanks for your answer.
I tried to use benchmark_rate, and I don’t have any sample loss at 200MS/s.

In both cases, the CPU load of each core never goes over \~25%.

Hi all,
I try to use a USRP X300 with a 10G Ethernet link at full speed (200MS/s),
running uhd 3.15.0 and gnuradio 3.8.2.
I followed all the tips from
https://kb.ettus.com/USRP_Host_Performance_Tuning_Tips_and_Tricks
but I still receive "O"s from time to time.
I don't have these messages at 100MS
