Re: Controlport

[Jeff Long]

That code, which is not often used these days, should be

  gr.prefs().set_bool(...) without the singleton() part

You could add an issue. That file is the only one left using the old method, which shows how much it is used or tested.

There is not any convenient way to get latency figures from within GR. Latency is somewhat controllable by setting maximum output buffer sizes and/or using the limit feature on the Throttle in more recent versions.

Is there any inbuilt gr_profilers in gnuradio to measure buffer,latency if not how can i get the benchmark values for comparison.

getting this error while using Ctrlport Performance Monitor in GNU Radio 3.10.8.0.

it will be very helpful if someone can help me to clear this
