On the powerful host with intel core i9 13900k, with 24 cores (Ubuntu
22.04 system) I installed DPDK, UHD v4.4.0.0, GNU Radio v3.10.7.0.
USRPX410 is connected by10GbE link (intel X710-DA4 card) to host. I
also set all the tuning for high performance.
benchmark TX/RX can work well with almost perfect without any errors
even up to 245.76MHz.
When I run GNU Radio, receiver works well for high sample rates. but
for transmit side, since I am generating triangular FMCW waveform,
chirp, with using triangular signal source and VCO, I see several
underrun for higher sample rates more than like 50Msps. Any suggestion?

You might post to discuss-gnuradio, since this is squarely a Gnu Radio
performance issue.
