In 2008 Many Faces was getting about 25k light playouts per second on 19x19. Today it gets 2500 playouts per second on one thread of an i7-3770. I don’t use a probability distribution in the UCT tree. I both count liberties and maintain lists of liberty points, but all incrementally. In the playouts I use 3x3 patterns with gammas like Crazystone, not just the Mogo patterns, but I only do a partial distribution. I also do local ladder searches and many other local tactics things.
