4x4 scramble generation takes a long time

[GhostShadow0316]

other scrambler I tested generates less than 1s but only 4x4 takes over 3s any ways to fix it?

i think that for 3x3 and 4x4 it its random state generator and for higher is random move scramble RSG - random state generator is generating random valid state, solving it, and reversing alg and random move are just random moves, i think this is used for bigger NxN cubes because you are more likely to get with scrambled end state. please correct me if i am wrong
