Possibly create (not sure if one already exists publicly) a plugin that will transfer larger quantities of items from hoppers. If 16 or so items were transferred every tick instead of just 1, it would cut down on a lot of lag on the server (I think?) and also would make it so items don't get backed up inside of hoppers. Right now, items in my hoppers are getting backed up because they aren't able to be transferred fast enough. Also, it could be toggled in claims so that people who use hoppers as a timer could still use it.
