Check out my first public minecraft mod ever. Currently, under review.
This mod was made with the Create Mod in mind, but really works for any Server that ends up with lots of dropped Items.

Smart Item Deleter v2 is a server-side optimization mod designed to automatically clean up dropped item entities when the item count exceeds a defined threshold.
It tracks items individually to ensure fair, efficient, and safe removal — deleting only excess, old, and unimportant drops without disrupting normal gameplay.
