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?
