Hello, It seems that I have to answer my own question. Currently I succeeded to get 245.76MSamp/s in benchmark_rate for single channel with DPDK over single 10Gbit link for an RFSoC device similar to USRP X410.
My setup: * UHD 4.3, Ubuntu 20.04, DPDK 19.11 installed from packages * command: benchmark_rate --rx_subdev "A:0" --rx_channels 0 --args="addr=192.168.10.2,mgmt_addr=192.168.0.39,use_dpdk=1" --rx_rate 245.76e6 * Hardware: AMD Ryzen Threadripper 2990WX, 128GB RAM, motherboard Asus X399 This is not a mind-blowing rate, because I’m able to get quite stable 245.76 MSamp/s without DPDK. But it is a good start taking into account number of different strange steps during DPDK installation and setup and very poor performance at the beginning. Solutions to some issues were totally counterintuitive. I.e. in the end I still had one \~oveflow per second at 245.76MSamp rate. The solution was to run the program WITHOUT root rights/sudo (what requires additional steps that were described by Rob Kossler). —\ Best Regards,\ Piotr Krysik Piotr Krysik wrote: > Hello all, > > Has anybody tried to use DPDK with USRP X410? > > If yes - can you share what was maximal sample rate for a single channel > that you were able to stream over 10G or 100G Ethernet connection > without loss and what was your setup (hardware and software)?
