Just lower the amount because if someone is breaking chests full of stuff it lags the server especially if there are a lot of items. Lower the limit of ground items to 1.5k or 2k because it will clear the items at a slightly lower amount and why not
There really is no point to this. If someone is making a load of entities be on the ground clear lag (clag) will remove them all, once its limit has been reached (Think its about 2600 right now). The server also has stacked entities in placed, so having 500 - 1000 less entities isn't really that much if you think about it. If they are all the same item which they probably are (if not that's impressive that they are able to place 500+ different entities on the ground) they will stack. For example 1024 items of the same block are only 16 entities (could be wrong but I think that's how it works). The increase serves no purpose other than giving devs another useless task to work on and make people angry when clag takes there item.
