Greetings,
I am trying to lock L1 bands of multiple gnss constellations simultaneously using gnss-sdr.org, for that I need atleast 56MHz, however, setting the sampling rate to 56MHz causes buffer overflow. Now it would make sense if I had a shitty pc however that is not the case. Infact, when I am receiving data from USRP using the benchmark_rate, cpu usage is only 2-3percent. I followed these instructions but they didnt resolve the issue. I get no overflow on 30MHz tho.
My NIC is Intel Corporation Ethernet Controller I225-V.
Sorry if this is the wrong place to ask this question.

Hi
You should use a 10GbE ethernet card.
ex. Intel X510DA2, X710DA2, E810
The I225-V has a transfer limit of 1Gbe.
