[Discuss-gnuradio] ANCI-C vs Gnuradio/C++ speeeed

I have noticed a huge speed dissadvantage when comparing my
ANSI-C implementation of a Viterbi decoder with my Gnuradio implementation. The core code is pretty much the same, except
that in the Gnuradio implementation I am using STL vectors.

It seems that Gnuradio is about 20 times SLOWER than ANSI-C!!!
I was wondering if this has to do with Gnuradio itself (buffering +
python + other fat), or with the fact that I had to translate all
my ANCI-C code to C++ and use STL.

Does anyone have similar experiences?
