Lag Removal
Lag Removal is a server-side Fabric utility that clears excess loaded entities on a timer, with a blacklist for entities that must stay.
What it does
On a Fabric server, the mod runs an automated clear-lag routine that periodically removes loaded entities to reduce the load caused by large numbers of them. Server owners can change the delay between automatic cleanup runs, turn warning messages before a cleanup on or off, and choose which entity types are protected. Named entities can be kept even when they would otherwise be removed. The mod is designed for multiplayer servers rather than single-player play, though it can technically run there.
Only the server needs the mod installed; players join normally without installing anything on the client. Configuration files are generated automatically on first launch, and the main settings file, config.json, sits in the mod's configuration folder. This project builds on the earlier Lag Removal mod by SWDTeam, and the author asks players to back the original makers. Lag Removal is not open source and is released under All rights reserved. Files are published for Fabric, across two release versions, 1.20.1 and 1.21.5, with 12.0.0 for 1.21.5 as the latest file.
