Hi, Concerning DCs, it might be only T3 which consumes a lot of CPU. I is due to the high background. To give you a better filling of the problem I plotted inclusive hit distribution in T3, T4 and T5 (see attached plots) (run 9368). Note, that the cpu for the tracking of one even scales with (hit_muli)^2 (at least). Nevertheless, I will try to optimize T3 tracking for large hit multiplicity conditions.
