In February 2016, scientists from the Laser Interferometry Gravitational-Wave Observatory (LIGO) announced the first ever observation of gravitational waves—ripples in the fabric of spacetime. This detection directly confirms for the first time the existence of gravitational radiation, a cornerstone prediction of Albert Einstein’s general theory of relativity. Furthermore, it suggests that black holes may occur…

So, it seems that optimizing a given code by hand is a no-go, as is starting from scratch. Still, you have to wonder if that is where the real speed-up is.
