>will this progressive change of contact stiffness really be faster then
using real material right from beginning?

Yes, definitely, if it is used the right way. Typically, you want to
increase stiffness each 10 steps or so. If you increase at each step the
loop for updating contact properties could take a significant time.

Yet, it is maybe not the best/simplest method. Actually, the computation time in your gravity deposition is ruled by gravity/stiffness. So, it would probably give the same benefit to increase gravity during deposition than to decrease stiffness.
Like for stiffness, you have to release gravity progressively in order to avoid explosions. The difference is that you don't have to take care of materials/interactions.
newton.gravity *= 0.99 #simple enough
