Description
🚀 Lagless: Servers
Lagless: Servers is a lightweight, high-efficiency utility mod designed to optimize RAM usage and keep your Minecraft 1.20.1 server running smoothly. By intelligently monitoring memory consumption, it helps prevent lag spikes and crashes caused by memory exhaustion.
🌟 Key Features
Smart Automated Cleanup: The mod periodically checks your server's RAM usage. If it exceeds a predefined threshold, it automatically frees up memory and clears unneeded temporary objects.
Server-Side First: You only need to install this mod on your server. Players do not need to have it installed on their clients to join! (Note: It can also be used in single-player for local optimization).
Zero Lag Impact: The verification system is designed to be lightweight, running seamlessly in the background without freezing the main server thread.
📊 Performance Benchmarks:
During local server tests (IntelliJ IDEA environment), the mod achieved a memory reduction of 366MB (6%). In other heavier scenarios, the cleanup process successfully freed up to 14% of the total RAM in use.
⚙️ Commands
/forcecleanup
Manually forces an immediate memory cleanup.
Displays exactly how much RAM was freed, along with the "Before" and "After" usage stats.
🔧 Configuration
The mod generates a lagless-server.toml file in your config folder, allowing you to fully customize its behavior:
autoCleanup (Default: true): Enable or disable the automatic memory management system.
cleanupInterval (Default: 300): How often (in seconds) the mod checks the RAM usage.
memoryThreshold (Default: 80): The RAM usage percentage that will trigger the automatic cleanup.
