AntiRedstoneLag

The Ultimate High-Performance Redstone Lag Prevention for Modern Minecraft Servers

⚡ About AntiRedstoneLag

AntiRedstoneLag is a lightweight yet extremely powerful plugin designed to safeguard your server from redstone-based lag machines and accidental over-engineering. Unlike basic limiters, AntiRedstoneLag uses asynchronous logging and O(1) tracking structures to monitor redstone activity with zero impact on your server's tick rate.

✨ Features

🚀 Asynchronous Foundation: Logging and timestamp generation are offloaded to background threads.
🎯 O(1) Chunk Cleanup: Refactored tracking logic for instant cleanup during chunk unloading.
🌈 Modern UI: Full migration to Adventure API and MiniMessage for beautiful, hex-color alerts.
🛡️ Lag Guard 1.21: Specifically optimized for Paper 1.21+ physics and redstone handling.
⚙️ Smart Actions: Choose between REMOVE (with physics notifications), DROP, or DISABLE.
📊 Persistent Analytics: Statistics tracking that survives server restarts.
🔄 Automated CI/CD: Development builds published automatically via GitHub Actions.

🚀 Performance Specs

Optimization	Method	Impact
Tracking	Nested Concurrent Maps	O(1) Chunk Cleanup
Messaging	Adventure API	Hex & Gradient Support
Logging	Async Timestamping	Zero Main-Thread Overhead
Memory	Fastutil Collections	Reduced Boxing/GC Pressure

📦 Installation

Download the latest release from Modrinth or GitHub.
Place the .jar in your server's plugins/ folder.
Restart your server.
Configure limits in plugins/AntiRedstoneLag/config.yml.

Requirements: Paper, Spigot, or Purpur 1.21.1+ and Java 21.

🛠️ Configuration

Modern power and simplicity. AntiRedstoneLag supports MiniMessage hex codes (<gold>, <#ffcc00>, etc.) in all messages.

View Optimized config.yml

# Thresholds
chunk-threshold: 500      # Max redstone updates per chunk per resetting interval
block-threshold: 15       # Max updates per individual block before action

# Reset interval in ticks (20 = 1 second)
reset-interval-ticks: 20

# Action when threshold exceeded: REMOVE, DISABLE, or DROP
# REMOVE: Clears block (Recommended)
# DISABLE: Cancels active signals
# DROP: Breaks block and drops items
removal-action: REMOVE

# Warning system
warning:
  enabled: true
  threshold-percent: 80   # Warn at 80% of threshold

# Alerts
alerts:
  enabled: true
  log-to-console: true

# Logging
logging:
  enabled: true
  performance-stats: true

2.0.1Релиз1.21.9, 1.21.10, 1.21.11 · 11 апреля 2026 г.

Bug Fixes Implemented:

Resolved Redstone Duplication: Added a "state check" to the removal logic. The plugin now verifies if a block is already AIR before attempting to drop it again, which prevents fast redstone clocks from spawning multiple items in a single tick. Fixed Ineffective Actions (REMOVE/DISABLE): Previously, the plugin was removing blocks without physics updates, which created "ghost blocks" and didn't stop neighboring redstone components. Now updated the logic to use applyPhysics = true. This ensures the Paper/Spigot physics engine is properly notified, immediately breaking the redstone chain and ensuring the client-side view stays in sync.

2.0.0Релиз1.21.9, 1.21.10, 1.21.11 · 12 декабря 2025 г.

Version 2.0.0

Bug Fixes

Fixed version mismatch - Synchronized pom.xml version with plugin.yml (both now 2.0.0)
Fixed unused variable - Removed unused materialName variable in RedstoneListener
Fixed stats command - /arl stats now shows real statistics from CounterManager instead of hardcoded zeros
Fixed unused imports - Removed unused imports from CommandHandler and RedstoneListener
Fixed potential NPE - Added null check for location.getWorld() in CounterManager.sendAlert() to prevent crashes with unloaded chunks
Fixed event priority - Changed from MONITOR to LOW priority since we modify block state
Fixed log download - /arl logs download now shows log file info (name, size, path, modified date)

Optimizations

Thread-safe counters - Replaced HashMap with ConcurrentHashMap and AtomicInteger for thread safety
Memory-efficient keys - Using String keys instead of Chunk/Location objects to prevent memory leaks
Extracted time constants - Magic numbers replaced with named constants (TICKS_PER_HOUR, TICKS_PER_DAY, DAY_MS, ALERT_COOLDOWN_MS, BATCH_SIZE, FLUSH_INTERVAL_MS)
Cached config values - RedstoneListener now caches redstone materials, enabled worlds, and removal action for better performance
Refresh cache on reload - Cached values are automatically refreshed when config is reloaded
Reduced object allocation - Avoid creating Location objects in hot path; only create when actually needed for logging
Batched log writes - Log entries are buffered and flushed every 50 entries or 500ms instead of on every write
Improved log rotation - Log file size is now checked on every flush, not just during cleanup task
Primitive collections (fastutil) - Replaced ConcurrentHashMap<String, AtomicInteger> with Object2IntOpenHashMap to eliminate boxing overhead and reduce memory allocations

New Features

Bypass permission - Players with antiredstonelag.bypass permission can place redstone without limits
Block owner tracking - Tracks who placed redstone blocks for bypass permission checks
Configurable reset interval - New reset-interval-ticks config option (default: 20 ticks = 1 second)
Debug mode - New debug config option for verbose logging during troubleshooting
Config validation - Threshold values are now validated (must be positive)
Alert cooldown - 1 second cooldown between alerts to prevent spam when multiple blocks are removed
Persistent statistics - Statistics (totalRemovals, removalsToday) are saved to stats.yml and survive server restarts
Configurable removal action - New removal-action config option with three modes:
- REMOVE - Set block to air (default)
- DISABLE - Cancel redstone signal without removing block
- DROP - Break block and drop item
Warning system - Warns players when their redstone activity approaches the threshold
- Configurable warning threshold (default: 80% of limit)
- Per-player cooldown to prevent spam
- Only warns block owners who are online
Update checker - Automatically checks for new versions on SpigotMC
- Notifies admins with antiredstonelag.admin permission on join
- Non-blocking async check on startup
Whitelist mode - Only monitor specific chunks instead of all chunks
- Configure chunks as world:chunkX:chunkZ format
- Useful for monitoring only known problem areas

Improvements

Real-time statistics - Stats command now displays actual monitored chunks, blocks, total removals, and daily removals
Better code structure - CommandHandler now receives CounterManager via dependency injection
Improved config comments - Better documentation in config.yml
Stats saved on shutdown - Statistics are automatically saved when the plugin is disabled
Null safety - Added null checks to CounterManager methods to prevent potential NPEs
JavaDoc comments - Added documentation to key methods

New Permissions

antiredstonelag.bypass - Bypass redstone limits (default: false)
