In a real app, the data size would be much longer (there's no need to optimise otherwise), that data would be rewritten for each iteration (no need to redo the calculation otherwise), and the work would not be done in a single long run but be divided over a number of e.g. jack process callbacks. I've again performed some tests on zita-convolver used by jconv to do the York Minster config. That means around 240 different blocks of 8192 complex values each. The differences between plain C++, hand vectorized, and optimised assembly code are absolutely marginal in that case.
