SyncBoost is not just another "lag clear" plugin; it is a comprehensive, professional-grade performance engine. Re-engineered for maximum efficiency, SyncBoost targets the root causes of server degradation—identifying CPU bottlenecks, memory leaks, and excessive entity overhead—allowing your server to sustain high player counts without compromising gameplay quality.
- ✨ Premium Experience: A stunning, modern GUI that brings visual elegance to server management.
- 🔧 Intelligent Automation: Dynamic algorithms that sense lag spikes and proactively adjust server load.
- 🗑️ Surgical Optimization: Reduce AI overhead, optimize redstone, and limit entities with pinpoint accuracy.
- 📊 Deep Monitoring: Real-time MSPT charts via interactive maps and detailed hardware benchmarks.
- ⚡ Asynchronous Core: Built to be ultra-lightweight, ensuring the optimization process never burdens your server.
Important
SyncBoost is optimized for modern Minecraft infrastructure (1.20.5 - 1.21.x) but also fully supports legacy versions (1.17.1 - 1.20.4). Recommended Java 21, minimum Java 17.
| Requirement | Version |
|---|---|
| Java | 17 or newer (Required) |
| Minecraft | 1.17.1 - 1.21.4+ |
| Server Software | Spigot, Paper, Purpur, Pufferfish, Folia, or compatible forks |
SyncBoost is modular by design. Enable or disable features as needed via the in-game GUI or modules/ config files.
| Module | Impact | Description |
|---|---|---|
| MobAiReducer | 🔴 Very High | Optimizes creature pathfinding and AI behavior. Essential for farm-heavy survival servers. |
| EntityLimiter | 🔴 High | Enforces limits on entity counts. Features Smart Mob Cap effectively balancing mob density based on server TPS. |
| LagShield | 🔴 High | Active monitoring that triggers safety measures (e.g., pausing spawners) when TPS drops critically. |
| ExplosionOptimizer | 🔴 High | Efficiently handles TNT and crystal explosions to prevent physics ticks from stalling the main thread. |
| ChunkAnalyzer | 🔴 High | Scans and identifies problematic chunks with high entity/tile entity counts. Features interactive GUI with teleportation. |
| WorldCleaner | 🟡 Medium | Periodically removes ground items. Features an "Abyss" system for item recovery via /abyss. |
| RedstoneLimiter | 🟡 Medium | Detects and suppresses rapid-pulsing redstone clocks that cause TPS drops. |
| VehicleMotionReducer | 🟡 Medium | Optimizes boat and minecart collisions, movement logic, and removes mineshaft clutter. |
| AbilityLimiter | 🟡 Medium | Limits rapid Trident/Elytra usage to prevent excessive chunk loading. |
| HopperOptimizer | 🟡 Medium | Reduces hopper tick rates and optimizes item transfer logic to minimize lag. |
| InstantLeafDecay | 🔵 Low | Makes leaves decay instantly when trees are cut, reducing entity processing. |
| ConsoleFilter | 🔵 Visual | Regex-based filtering to keep your server console clean and readable. |

SyncBoost anonymously collects data via bStats to help us improve performance.
You can disable this in plugins/bStats/config.yml.
Configuration is split into:
config.yml- Main plugin settings (prefix, permissions, updater).lang.yml- All user-facing messages.modules/*.yml- Individual module settings.
You can edit configurations directly in-game using the GUI:
/syncboost
- Download the latest
SyncBoost.jarfrom Modrinth. - Stop your Minecraft server.
- Place the jar into your
plugins/folder. - Start the server.
- Configure via
/syncboostor edit files inplugins/SyncBoost/.
