Re: [Discuss-gnuradio] Profiling GNU Radio flow graphs

[Carles Fernandez]

Hi Felix,

we have some notes on code profiling here:
http://gnss-sdr.org/documentation/how-profile-code

We use the tools described there in a C++-only flowgraph, but I hope
some of them will also work for you.

Best regards,
Carles
