[Discuss-gnuradio] Comparison of filters in C++ vs Python

[Jim Borynec]

Hi,

Has anyone determined the basic overhead of a filter?
I can't help but feel that stringing two filters in a row
(e.g. one to add a value and the other to multiply something)
would be less efficient than a single filter which does both operations 
internally.

Does the overhead of a filter basically swamp the computation involved?

I understand the advantages of being able to quickly assemble a complicated 
filter from simpler filters.

Also, has anyone quantified the cost advantage to using C++ (as compared to 
Python).

Is a single Python filter (which does an add and a multiply internally) more
efficient than two C++ filters strung together?
