[Discuss-gnuradio] Testing an GRC project runs nearly 200% CPU

[Andreas Ladanyi]

Hi,

iam testing an UKW Radio Receiver GRC project (gr-rds) on bananapi. The 
application starts. The tuned radio station sounds clicking. Changing 
any parameter in the GUI is very difficult/slow.

top tells me a memory usage about 20 %. CPU usage is nearly 200 % 
(bananapi has 2 CPUs). At any webside i read that working with no 
throttle blocks could run a CPU to maximum. In my project which iam 
testing i see no throttle blocks. I am not sure if that could be the 
reason because iam working on the bananapis real hardware ?

Is there something wrong with the sample rate ?
