Comment 6 for bug 1853638

I am an engineer at Broadcom and have been assigned to investigate this issue. To that end, I have a few clarifying questions:

1a) What is the benchmark tool you are using and could you provide a link to where I can get it?

 b) What kind of network traffic is it sending?

2a) In what units are the data rate parameters "--rx_rate 10e6 --tx_rate 10e6" specified?

 b) What data rate are you attempting to send? The report notes that the platform can't be the issue at 1G, but are you attempting to utilize 10G?

3) Perhaps stating the obvious here, but has anybody looked into the warning?

"[WARNING] [UHD] Unable to set the thread priority. Performance may be negatively affected."

which is probably related to this error:

"EnvironmentError: OSError: error in pthread_setschedparam"

4 a) I am personally unfamiliar with the USRP x310, could you provide some more information about it? Googling for it seems to indicate it is some kind of software defined radio platform?

  b) Is there a way to get access to one to reproduce and diagnose this issue?
