AntiLag+

▸ THE PERFORMANCE TOOLKIT

AntiLag+ is an advanced server performance toolkit built for modern Minecraft servers.

Instead of relying on a single cleanup command, AntiLag+ combines real-time performance monitoring, configurable optimization modules, entity control, automatic cleanup, performance alerts, and protection systems into one lightweight plugin.

Designed to help you find performance problems before they become serious.

Measure the server. Detect the pressure. Optimize what matters.

▸ REAL-TIME PERFORMANCE MONITOR

Know what's happening inside your server.

Tracked Metrics:

• TPS — Server tick performance
• MSPT — Tick processing time
• CPU — Processor usage
• Memory — JVM memory usage
• Entities — Entity population
• Chunks — Loaded chunk information
• Worlds — Per-world statistics
• Performance History — Recent performance data

AntiLag+ can detect performance degradation using configurable TPS and MSPT thresholds.

▸ SMART PERFORMANCE ALERTS

Don't wait until players start complaining about lag.

AntiLag+ can monitor server health and trigger alerts when performance reaches configured levels.

Configurable thresholds:

• TPS Warning
• TPS Critical
• MSPT Warning
• MSPT Critical
• Severe MSPT
• Critical MSPT Spike

This gives administrators a clear picture of when the server starts entering a degraded state.

▸ MODULAR OPTIMIZATION ENGINE

AntiLag+ is built around configurable optimization modules.

Enable, disable, and tune individual systems instead of changing everything at once.

Mob AI Reducer
Reduces unnecessary mob AI processing when players are outside the configured radius.

Entity Limiter
Controls excessive entity density with configurable per-chunk limits and overflow handling.

LagShield
Applies configurable protection thresholds when server TPS drops.

Hopper Optimizer
Provides hopper throttling, chunk limits, and empty-hopper delay controls.

Redstone Limiter
Controls excessive redstone updates per chunk and tick.

Explosion Optimizer
Limits explosion activity and provides configurable block reduction.

Vehicle Motion Reducer
Throttles unnecessary processing from empty vehicles.

Ability Limiter
Adds configurable cooldown protection for Elytra boosts and Riptide usage.

Instant Leaf Decay
Speeds up leaf decay with a configurable per-tick limit.

Trash Disposal
Controls old ground items with configurable lifetime and blacklist support.

World Cleaner
Provides configurable cleanup for items, projectiles, XP, and optionally mobs.

Console Filter
Reduces noisy console spam without intentionally hiding security-critical errors.

▸ SMART ENTITY MANAGEMENT

Large entity populations can become a major source of unnecessary server workload.

AntiLag+ provides configurable controls for:

• Creatures per chunk
• Vehicles per chunk
• Projectiles per chunk
• Entity overflow
• Named entities
• Tamed entities
• Leashed entities
• Persistent entities

Important entities can be protected from automatic cleanup through configurable safety rules.

▸ AUTO-CLEAR SYSTEM

Need automatic cleanup?

AntiLag+ provides a configurable Auto-Clear system with safe defaults.

Supported cleanup categories:

• Ground Items
• Projectiles
• Experience Orbs
• Arrows
• Falling Blocks
• Vehicles
• Minecarts
• Boats
• Hostile Mobs
• Passive Mobs
• Item Frames
• Armor Stands

Safety Protection:

• Ignore named entities
• Ignore tamed entities
• Ignore leashed entities
• Ignore persistent entities
• World exclusions
• Entity exclusions

Auto-Clear is disabled by default, allowing server owners to configure exactly what should happen before enabling destructive cleanup.

▸ SMART CLEANUP

Don't want cleanup running blindly on a timer?

AntiLag+ supports performance-based cleanup conditions.

Configure cleanup to react to:

TPS ↓

MSPT ↑

You can also configure cooldowns and maximum removals per cycle to prevent aggressive cleanup.

▸ PERFORMANCE HISTORY

Lag isn't always permanent.

AntiLag+ can maintain recent performance history for easier diagnosis.

Track recent:

• TPS
• MSPT
• Performance changes
• Alerts
• World statistics

Retention time and history limits are configurable.

▸ OPTIONAL WEB DASHBOARD

Want performance information outside the game?

AntiLag+ includes an optional local web dashboard system.

Configurable options:

• Host / bind address
• Port
• Fallback ports
• Realtime updates
• Public access protection

The dashboard is disabled by default and uses a local-first configuration.

▸ FULLY CONFIGURABLE

AntiLag+ is designed for server owners who want control.

Configure:

• Monitoring intervals
• TPS/MSPT thresholds
• Entity limits
• Cleanup intervals
• Cleanup categories
• World exclusions
• Entity exclusions
• Protection thresholds
• Module settings
• Performance history
• Web dashboard
• Player preferences

▸ COMMANDS

Aliases:

▸ PERMISSIONS

▸ OPTIONAL INTEGRATIONS

PlaceholderAPI

Optional integration for placeholder-based functionality.

spark

Optional integration for additional server performance profiling.

Neither integration is required for the core plugin.

▸ COMPATIBILITY

Minecraft: Java Edition

API: Paper 26.2

Built for: Modern Paper-based servers

Folia: Not supported

AntiLag+ is compiled against the Paper 26.2 API. Compatibility with other Minecraft versions or server implementations should not be assumed unless specifically tested.

▸ PERFORMANCE WITHOUT THE GUESSWORK

AntiLag+ isn't designed to magically fix badly optimized plugins or poor server configurations.

It gives administrators the tools to:
