Need insight to how hopper/redstone activity is handled. in Servers Posted February 16, 2017 · Edited February 16, 2017 by AncientTom I think I just answered my own question by laying out this train of thought and pondering over it. As far as the hoppers sucking from above, floating entities by this time have already been stacked. Even at that, there are too many variables that may need time to be serviced and/or none of them may need servicing. Therefore there is probably no such thing as an average time to process a hopper on the server.
