LagScope
LagScope is a performance analyzer and lag control plugin for Paper and Purpur (1.21+).
Smart Lag Control
LagScope tracks TPS, MSPT, entities, chunks, and activity spikes.
- Detects lag-heavy chunks immediately.
- Identifies problematic mechanics (entities, redstone, explosions, hoppers).
- Applies targeted limits instead of global wipes.
- Offers multiple lag modes ranging from "Light" to "Aggressive."
The goal is a stable server without unnecessary interference with gameplay.
Active Protection Modules
The plugin is modular, allowing all optimizers to be toggled or tuned individually:
- Entity Limiter: Prevents entity and projectile spam per chunk.
- Entity Cleaner: Triggers smart cleanup when thresholds are exceeded.
- Explosion Control: Manages TNT and explosion spam.
- Redstone Limiter: Stops redstone clocks and massive update storms.
- Hopper Optimizer: Reduces hopper lag without breaking technical systems.
- Mob AI Optimizer: Scales down AI intensity based on server load.
- Vehicle Limiter: Limits minecart and boat physics spam.
- Action Limiter: Prevents abuse of items or abilities.
- Lag Protection: Automatically escalates measures based on current TPS/MSPT.
In-Game Analyzer & GUI
Identify the source of performance issues directly within the game:
- Live TPS and MSPT display.
- List of the most resource-intensive chunks.
- Entity and tile-entity counts.
- Module status overview.
Management is handled through an in-game GUI, reducing the need to manually edit configuration files.
Performance First
- Event-driven logic without unnecessary background tasks.
- Chunk-aware limiting avoids global punishment for all players.
- Built specifically for modern Paper and Purpur APIs.
- Safe for large SMPs and professional networks.
LagScope focuses on stability through intelligent management rather than simple destruction.
Commands
/lag – Open the performance overview GUI./lag clear – Manually trigger a smart cleanup./lag mode <light|normal|aggressive> – Change the optimization strength.
Ideal For
- SMP and Survival servers.
- PvP servers with high TNT or redstone usage.
- Large communities with high entity counts.
- Network and high-player-count servers.
