comparing scalar vs vector items

[Ali G. Dezfuli]

Hi all,
I'd like to compare two GR blocks in terms of performance (especially
throughput)
1- using scalar items together with "set_output_multiple
<https://www.gnuradio.org/doc/doxygen/classgr_1_1block.html#a63d67fd758b70c6f2d7b7d4edcec53b3>
(int multiple)" at the constructor, and
2- using vector items.
regards,
AGD
