Hello All Gnu Radio users,

After following some presentations of GNU Radio in FOSDEM, I decide to  
take GNU Radio platform again and do some implementations.

My question is how can i use CtrlPort and gr-perf-monitorx to calculate  
the processing time of each block within my flow graph ?

Thank you for your help.

Not at all, right now – CtrlPort is currently disabled. You can find  
info on this by searching the mailing list archives.
