Minecraft servers with plugin LagFixer

## 🔌 About LagFixer LagFixer — is a plugin for Minecraft servers that allows server operators to reduce lag by optimizing entity AI, item accumulation, explosions and redstone behavior. It addresses common server‑side causes of TPS drops and high MSPT but does not fix issues caused by poorly coded third‑party plugins or insufficient hardware. ### 🎯 Purpose LagFixer is made to improve server performance by: - reducing expensive mob AI and movement calculations (MobAiReducer), - cleaning up dropped items and handling an "abyss" where removed items are stored, - limiting entities per chunk (EntityLimiter), - dynamically reacting to high load spikes (LagShield), - limiting redstone/ability/vehicle costs and optimizing explosions. () ### ⚙ Main features - Modular optimizers (MobAiReducer, EntityLimiter, ItemsCleaner/WorldCleaner, ExplosionOptimizer, RedstoneLimiter/AntiRedstone, VehicleMotionReducer, AbilityLimiter, ConsoleFilter, LagShield). () - In‑game configuration menu for quick adjustments. () - PlaceholderAPI placeholders: %lagfixer_tps%, %lagfixer_mspt%, %lagfixer_cpuprocess%, %lagfixer_cpusystem%, %lagfixer_worldcleaner%. () - bStats metrics integration. () ### 🧩 Who it's for LagFixer fits server owners and admins who run Paper/Purpur/Pufferfish/Spigot servers (also lists Folia support) and need a lightweight performance tool to control mob and entity behavior, clean items, and mitigate redstone/ explosion related lag. It is intended for production servers but is not a replacement for profiling and fixing poorly coded plugins. () ### 🏗 Examples of use - Use MobAiReducer to reduce CPU pressure on farms with many animals. () - Configure WorldCleaner / ItemsCleaner to remove old dropped items and allow players to reclaim items from the /abyss. () - Enable ExplosionOptimizer on servers with frequent TNT or crystal usage to avoid massive TPS drops. () ## ⚡ Notable integrations & compatibility - Supported platforms: Paper, Spigot, Purpur and Folia (listed on Modrinth). () - Java 8 or later; tested for Minecraft 1.16.5 → 1.21.x (exact supported build ranges listed on project pages). () - Optional integrations/support: PlaceholderAPI and several stacker plugins; does not state Vault as a requirement.

() ## 🔐 Permissions | Permission | Опис | Default | |---|---|---| | Information not specified in official sources | The project's public pages (Modrinth / Spigot) list commands and features but do not publish the full permission node table. Please consult plugin documentation or repository for exact permission nodes. | - | ## ⚙ Installation ### 📥 Installation - Download the LagFixer .jar from the official plugin page (Modrinth or Spigot). () - Place the .jar into your server's plugins/ folder. - Restart the server (recommended full restart, not /reload). - Use `/lagfixer menu` or check docs for configuration options. () ### 📦 Dependencies - Optional/Supported integrations: PlaceholderAPI (listed), compatibility with certain stacker plugins and Spark for profiling. bStats is used for metrics. The plugin does not list Vault as a hard dependency on the official pages. () ### 🧾 Configuration - The plugin provides an in‑game configuration menu for quick changes. The official pages reference configuration controls but do not publish a detailed config.yml example on the listing pages; refer to the project documentation for full config options. () - MySQL/SQLite support: not documented on the public Modrinth/Spigot pages. If database support is required, check the plugin docs or GitHub repository. () ## 🧠 Additional information ### Known issues / reported behavior - Several reviews report aggressive item/entity clearing that removed tamed animals or more entities than expected; adjust WorldCleaner / entity rules carefully. () - Some users reported chat spam from the plugin until config is tuned. () ### Limitations - LagFixer can reduce common causes of lag but cannot fix bugs in third‑party plugins or replace proper profiling. Use with care on large production servers and test in staging. () ### FAQ **Q: Which Minecraft versions are supported?** A: Public listings show testing/support for 1.16.5 through 1.21.x (check the specific build compatibility on the download page). () **Q: Does LagFixer use PlaceholderAPI?** A: Yes — it publishes PlaceholderAPI placeholders (TPS, MSPT, CPU usage, worldcleaner countdown). () **Q: Does the plugin send metrics?** A: Yes — the project uses bStats for anonymous metrics. () **Q: Is Folia supported?** A: The Modrinth listing and project notes mention Folia support. Test modules individually — Folia support may vary by module. () **Q: Where to report bugs or get support?** A: The project links to an official Discord for support and to its documentation (GitBook). () --- When evaluating LagFixer on your Minecraft server, keep in mind it is a performance utility (minecraft plugin / paper plugin / spigot plugin) that changes entity behavior and cleans the world; configure conservatively and test to avoid unintended removals. LagFixer (the plugin name) appears across Modrinth and Spigot listings and includes modules and commands described above; consult the project documentation for exact permission nodes and advanced configuration.
