Hi Readers,

My PC has 2 gigabit ethernet controlers. I read data from USRP2 (UHD, COMPLEX_FLOAT32, sample rate = 2.5 MHz) and sent it to another PC via UDP protocol.

If I sent data to another PC directly (use IP address), in System Monitor view : Receiving = 10.0 MiB/s; Sending = 19.6 MiB/s.
uhd_src = uhd_make_usrp_source(dev_addr, uhd::io_type_t::COMPLEX_FLOAT32, 1);


    udp_dataSender = gr_make_udp_sink(sizeof(gr_complex), "", udp_port, 1472, true);

    tb->connect(uhd_src, 0, udp_dataSender, 0);
