Little update: currently with the same setup but with different clocks configuration I can record 256MS/s. This is with use of single 10GbE connection. I can’t use multiple connections simultaneously to transfer more channels with maximum rate yet. If someone tried that with USRP X410 I would be grateful for information how it worked (or didn’t work). Best Regards,\ Piotr Krysik
