Hi, This issue is better addressed to usrp-us...@ettus.com. Briefly I can tell you that you can never reach 30M samples/sec over a 1 GbE interface. 30 x 32/bits/sample = 960. Need a bit for metadata, packet overheads, etc. you will drop packages. Especially if your NIC is PCI based :( Try reducing your sample resolution to 8 bits. You may have better luck.
