LagLess

LagLess is a lightweight yet powerful Minecraft server performance and optimization plugin designed to help server owners reduce unnecessary entity load and maintain a smoother, more stable gameplay experience.

LagLess continuously monitors your server and provides configurable optimization systems for entities, mobs, dropped items, and loaded chunks. Instead of forcing a fixed optimization strategy, LagLess gives administrators control over how aggressive the optimization should be through an easy-to-edit configuration file.

Features ⚡ Entity Optimization

LagLess monitors entities across your worlds and can help prevent excessive entity buildup. Administrators can configure limits for entities inside individual chunks to reduce unnecessary server workload.

🧹 Item Cleanup

Dropped items can accumulate quickly and create unnecessary server load. LagLess can automatically remove items that have been lying on the ground for a configurable amount of time.

🐄 Mob Limits

Configure maximum amounts of specific mob types per world. This helps prevent extreme mob accumulation while allowing important entities such as villagers, pets, and other protected entities to remain unaffected.

📦 Chunk Entity Management

LagLess monitors loaded chunks and checks their entity counts. When a configurable limit is exceeded, the plugin can reduce unnecessary entities while protecting players and persistent entities.

📊 Server Statistics

Use simple commands to inspect your server's current entity and chunk situation:

**/lagless status

/lagless entities

/lagless reload**

⚙️ Fully Configurable

Almost every optimization can be customized through config.yml. Server administrators can enable or disable individual systems and adjust limits and cleanup intervals to match their server.

🔄 Live Configuration Reload

Configuration changes can be applied without restarting the server using:

/lagless reload

Designed for Performance

LagLess is designed to remain lightweight and avoid unnecessary processing. Optimization tasks run at configurable intervals rather than constantly scanning the server every tick.

The goal is simple: less unnecessary server work, fewer entity-related performance problems, and a smoother Minecraft server experience.

Server-side plugin
