Re: [Discuss-gnuradio] Clock block slow in position satellite calculation

[Marcus Müller]

Hi!
You shouldn't use so many throttles in one flow graph; throttle limits
the number of samples going through in a given time, and as soon as the
"upstream" blocks have filled their output buffer, they will be limited
in throughput, too.
So I guess this is the effect of throttles blocking each other; however,
I don't really understand what's happening inside your flowgraph, so
this is a lot of guesswork.

Greetings,
Marcus
