LagScope

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.
