here is the experiment where they now really do this na s benchmark and they compare with other methods so some of these other methods are designed to do they call it weight sharing which basically is a technique where you can sort of speed up the speed up the algorithm as compared to non weight sharing and the non weigh cheering that's one of these we have discussed initially that was my initial example with the controller and so on where it takes super long so here you see the method and how long each method takes
