For user opcodes and instruments it depends a lot on how they are written. If
they do not contain feedback and they are executable block-by-block the
speedup is not bad, because instructions are vectorial. Otherwise the speed is
reduced, but the structure is optimized anyway. In these days Claudio is
expecially working on sample-by-sample execution, with appreciable sppedup
over our previous results.
