All the USRPs and my host are connected to the same Gig-Ethernet switch. If you feel that your USRP-to-Host networking bandwidth is the bottleneck, maybe you could try running your wireless experiments over a thinner channel to reduce the sampling rate, and hence, the data transmitted between the USRP and host. Good luck. Aditya
