OK.  Glad you (think) you solved your problem.

Given that your block was asked to compute noutput_items, why are you
only computing (and/or returning) noutput_items/(N*N) items?
Doing it this way is increasing the runtime overhead by something on
the order of N*N.

This smells like there's something that you don't understand about
io_signatures, forecast, work, set_output_multiple and/or gr_sync_decimator...
