Hi Chris, Thanks for your suggestion, I would like to try it out.
Hi Tom, Actually we are building a broadband OFDM system targeting at 20MHz. Now the transmit part can support 20MHz transmitting (set argument -W 20M), but the receive part will block and show overrun message once we set --sample-rate larger than 1M. We use Xeon w3530 and N210. I think the reason is: the code of receiver is inefficient thus unable to process the samples from USRP in time. Before optimizing the code, I should first find the bottleneck--which module chokes my system--from the whole system's perspective. That's why I want to profile python code rather than C++ code.
