It still is Cake underneath doing the work, autorate is ju= st adjusting available bandwidth to get the best latency at the best possib= le bandwidth. I would think it's the same limitation. I believe Dave Ta= ht mentioned possibly making cake take advantage of multiple cores in the n= ext version/rewrite of Cake.

One of the problems i've had with Cake is that it becomes C= PU bound beyond around 3 or 4 gigabit.
