In a general sense, yes, GNU Radio is well suited for real-time signal
processing of data streams. That said: "Real time" is only meaningful knowing
the performance criteria. What sort of performance do you require processing
for?

IIRC (Tom? Eric?): GNU Radio uses the standard C++ "new" command for most memory
allocations -- and thus it is memory from the heap. One can always overload
this method globally or locally if required, to provide memory from pools or
other means.

Yes. Your choices are a single thread for all or 1 thread per block. - MLD
