Dear Kobayashi-san, You want to make sure the size of the network packets is as large as possible to reduce overhead; UHD will print out the information of how many bytes are in a single packet during initialization. You might need to tell Linux that it needs to use a larger MTU (8000B should work

[USRP-users] High CPU load on UHD driver and Ether ISR

2017-09-22 Thread Kobayashi, Noboru via USRP-users
Hi, all I'm working in a LTE related system using Ettus X310, using UHD driver on CentOS 7.3 base real-time kernel patched environment. UHD driver version using is 3.9.6 Current master clock frequency is 184.32MHz, and sampling rate is 30.72MHz. 2 RX/TX antennas are used with 16bit I/Q
