There isn't any optimised diffuser on m1 yet most of them are just running basic MPS graph or even mix of CPU and MPS ops and ofc it is extremely slow I dont have time to test this implementation but author just use some other implementation with simple UI. So I would be surprise if it is faster than 10s per img with 20steps and probably more close to 25-40s and around 40s-1min per classic 512x512 50-60 step setting as are other models.
