LagFixer helps improve server performance by optimizing the Minecraft engine. It won’t fix all lag by itself, but it can noticeably reduce it when used with well-coded plugins and a solid server setup. It’s not meant to fix problems caused by low-quality or badly configured plugins.
› If you're not sure how to configure your server properly or which plugins to use, I offer paid help with optimization and plugin selection. Feel free to contact me via Discord for details.

Modules:

MobAiReducer: (Impact on performance: VERY HIGH)
- Replaces creature movement to optimize and reduce behavior.
- Addresses inefficiencies caused by default animal behavior like unnecessary random movements or constant looking around.
- LagFixer intervenes by disabling unnecessary PathFinders or replacing them with more efficient ones.
- Crucial in scenarios with numerous animals as even minor movements can strain server resources.

WorldCleaner (Impact on performance: MEDIUM)
- Cleans up old items on the ground to accelerate server performance.
- Accumulation of items over time contributes to server lag, especially in densely populated or active servers.
- Removes extraneous items promptly to relieve server burden.
- Players can retrieve items from the Abyss inventory using the /abyss command.

EntityLimiter (Impact on performance: HIGH)
- Restricts the number of entities per chunk.
- Essential for survival servers with expansive animal farms.
- Prevents excessive entity accumulation and associated performance issues.
- Maintains stable performance levels even in environments with high entity density.

LagMonitor (Impact on performance: HIGH)
- Monitors server load and adjusts settings during latency spikes.
- Addresses fluctuations in server performance to mitigate delays and lag.
- Dynamically adjusts settings, disables unnecessary features, and optimizes resources.
- Ensures smooth gameplay by minimizing the impact of performance fluctuations.

AntiRedstone (Impact on performance: LOW)
- Disables demanding Redstone clocks to prevent server overload.
- Certain Redstone configurations can lead to performance degradation and crashes.
- Activating AntiRedstone preserves server stability and ensures responsiveness.
- Facilitates uninterrupted gameplay even with complex Redstone contraptions.

ConsoleFilter (Impact on performance: VISUAL ONLY)
- Filters console messages based on predefined rules.
- Enhances clarity by selectively displaying essential messages.
- Reduces clutter and improves readability in multiplayer servers.
- Facilitates efficient server administration and enhances the user experience for both administrators and players.

VehicleMotionReducer (Impact on performance: LOW)
- Optimizes all vehicles such as Boats and Minecarts.
- Removes minecarts with chests spawned in mineshafts.
- Particularly useful when minecarts are frequently used on the server.
- Enhances server performance by optimizing vehicle mechanics and removing unnecessary entities.

AbilityLimiter (Impact on performance: MEDIUM)
- Limits rapid Trident and Elytra usage to prevent excessive chunk loading.
- Frequent high-speed travel can cause server lag and instability.
- AbilityLimiter allows adjusting the speed reduction to balance performance and player experience.
- Activating AbilityLimiter ensures smoother world loading, stable server performance, and controlled mobility.


PlaceholdersAPI:
› %lagfixer_tps% - Current ticks per second
› %lagfixer_mspt% - Current miliseconds per tick
› %lagfixer_cpuprocess% - Current process cpu usage
› %lagfixer_cpusystem% - Current system cpu usage
› %lagfixer_worldcleaner% - Countdown to world clean

Coming soon:

1. FpsHelper - Monitors packets sent from the server to the player and cancels those that may cause FPS drops.
2. CreatureStacker - Stacks mobs and items, reducing the number of computed entities.
3. CustomTracker - Overrides Bukkit's EntityTracker, optimizing and disabling ticking for untracked entities.
4. WorldOptimizer - Disables ticking for certain entities and unloads unused chunks.
